CSI: Why The Major Cast Members Left

The Cast Of CSI: Crime Scene Investigation

Shortly after its premiere on October 6th, 2000, CSI: Crime Scene Investigation became one of the most ubiquitous TV shows of the early 21st century. The popular series had 15 seasons on CBS, spawned several spin-off series, and played a major part in fueling our society's only growing fascination with true and fictional crime stories. Suffice to say, the broadcast TV show has had a major legacy in our collective pop culture in the new millennium. But everything needs to wind down at some point, and the series met its end in 2015. Likewise, not everyone from the cast stayed on-board throughout CSI's 15-year stint. The show's ensemble rotated in regular fashion. There were only a select handful who stayed until the finale.

It's hard to stay attached to one project for a long period of time. Sure enough, most of the actors involved with CSI exited over the extensive course of its television run. Some departures from the hit series were perhaps a little more controversial than others. Some exits were graceful. Others were not. Nevertheless, only a very few of the actors stayed on CSI from beginning to end. Here are the various reasons why each major cast member left.

William Petersen - CSI: Crime Scene Investigation

William Petersen

From the very beginning, William Petersen was one of the main characters at the forefront of CSI. In the role of Dr. Gil Grissom, he stayed on the show for nine seasons between 2000 and 2010, but the actor decided to leave the program at the start of the decade. Petersen opted to leave CSI in order to pursue more stage acting opportunities. While the actor enjoyed the experience, he felt fortunate for the chance to pursue other projects. In the time that Petersen exited the show, he has stayed on-board as an executive producer and made a return in a 2011 episode, plus the series finale.

Marg Helgenberger - CSI: Crime Scene Investigation

Marg Helgenberger

Marg Helgenberger was another series regular from the very beginning in the role of Catherine Willows. Additionally, Helgenberger's departure from CSI mirrors William Petersen's exit. She came on-board in 2000 and she stayed involved for 12 seasons. In 2012, however, she revealed that she was leaving the program to explore other opportunities away from the show. While she did make a brief cameo in season 14, Helgenberger was away until the series finale, where she returned alongside Petersen. During her time, she was one of the highest paid CSI stars.

Gary Dourban - CSI: Crime Scene Investigation

Gary Dourdan

As Warrick Brown, Gary Dourdan was similarly on CSI from the beginning. And similar to William Petersen, he left the series in season nine. Unlike his co-stars, however, Dourdan didn't return to the show later down the road. That's because his character died during the season nine premiere. As it was reported back in 2008, it came down to contract negotiations. The parties involved reportedly couldn't meet a resolution, and it was announced that Dourdan would leave the show. He has bounced back-and-forth between movies and TV since he left the popular show for good.

George Eads - CSI: Crime Scene Investigation

George Eads

In the role of Nick Stokes, George Eads has remained a familiar face on CSI throughout its long-standing run on television. And he stayed on the show for a good while too. Specifically, he was involved until the 15th season, which makes him on the very few actors who stayed on CSI throughout many seasons on television. That's certainly no small feat. He had plans to leave the series in 2014 alongside Elisabeth Shue, likely in an effort to explore different projects. There were also reports that Eads had a nasty dispute with a writer, which likely soured him from the experience of returning to the famous CBS series. In any case, it didn't make a difference since the show wasn't renewed for a follow-up season. Despite his long tenure on the program, George Eads wasn't in the series finale, the feature-length "Immortality," with William Petersen replacing him.

Paul Guilfoyle - CSI: Crime Scene Investigation

Paul Guilfoyle

Likewise, Paul Guilfoyle, who played Jim Brass, kept a long stay on CSI. The actor was involved in the first season, and he stayed on-board until Season 14, though the producers reportedly decided not to bring him on for the show's 15th and final season. As THR reported, it was the producers decision to not let him participate in the show's ultimately final season, and there are reports that the actor made an emotional farewell speech on his final day of production. But it wasn't goodbye for good, evidently. Specifically, Paul Guilfoyle returned to reprise his famous role in "Immortality." After CSI came to a close in 2015, Paul Guilfoyle still stayed connected to CBS. The TV actor currently plays a role in CBS' All Access' The Good Fight.

Jorja Fox - CSI: Crime Scene Investigation

Jorja Fox

While she previously received notice for her guest appearance on ER and her work on The West Wing, it was Jorja Fox's role as Sara Sidle that made the actress/musician well-known to television viewers everywhere. The actress played a role throughout the show's extensive run, with only a portion of time between 2008 through 2011 where she temporarily left the show. That changed when she became a main again in 2011, and she stayed on until it came to a close in 2015. Despite a short-lived absence from the dramatic series, Jorja Fox (mostly) stuck with her cushy CSI job until the end.

Eric Szmanda - CSI: Crime Scene Investigation

Eric Szmanda

While Eric Szmanda was more recurring than main during his first two seasons on CSI as Greg Sanders, the actor became a regular face throughout the show's weaving tenure. He officially became a main player during the show's third season, and that's what he remained until the show's final days.

Robert David Hall - CSI: Crime Scene Investigation

Robert David Hall

Likewise, Robert David Hall was only recurring throughout the first two seasons of the immensely popular CSI, but he was bumped up into the main cast around season three in the role of Al Robbins, and the TV actor remained one of the main players on the program until it came to a close in 2015.

David Berman - CSI: Crime Scene Investigation

David Berman

It took a good while for David Berman's David Phillips to get the main cast treatment. He was a recurring character from season one until season nine, but the commitment to the popular show paid off. He became a main player during season 10; that is what he ended up being until CSI's series finale.

Wallace Langham - CSI: Crime Scene Investigation

Wallace Langham

Wallace Langham didn't start playing the part of David Hodges until well after Season 3 of CSI was underway. Nevertheless, the actor became a permanent fixture on the show. He was a recurring character until season seven. Starting in Season 8, he was a main player until the show's finale.

Jon Wellner - CSI: Crime Scene Investigation

Jon Wellner

As Henry Andrews, Jon Wellner didn't become a CSI fixture until its fifth season was well underway. Nevertheless, after an extended period of being a recurring character, he was bumped up to series regular in Season 13. From there, the actor stayed a regular until his final scene in CSI's series finale.

Louise Lombard - CSI: Crime Scene Investigation

Louise Lombard

In the role of Sofia Curtis, Louise Lombard was first introduced to the world of CSI in Season 5. From there, the actress had an inconsistent record on the show. Specifically, she was a recurring character until Season 7, when she became a series regular. But it only lasted for one season. It was shortly thereafter that she served for a season as a recurring character before leaving the series after Season 8, only to make an appearance in Season 11. Nevertheless, Season 11 was the final time viewers saw Louise Lombard on the show. As for the reasons for his stark exits and returns, it might have to do with the star having children. Nevertheless, Lombard mentioned in an interview that she returned after being asked by a producer.

Liz Vassey - CSI: Crime Scene Investigation

Liz Vassey

Similarly, Liz Vassey only had one season where she was a series regular on CSI. In the role of Wendy Simms, Vassey was first introduced in Season 6 and she was a recurring character until Season 10 when she was promoted into being a series regular for one season. She was recurring character for a brief period in Season 11 before she left the show for good. Ultimately, according to Digital Spy, Vassey was let go when the show went in a new creative direction. It sounds like she ultimately didn't have a choice in the matter, with the producers rather unceremoniously letting the TV actress go.

Lauren Lee Smith - CSI: Crime Scene Investigation

Lauren Lee Smith

Lauren Lee Smith did get the opportunity to play a main player in Season 9 of CSI, but it was short-lived experience. In the role of Riley Adams, the actress was introduced in the season's third episode and she left in the season finale, never to return to the show. Ultimately, according to a producer on the show, Smith was let go because she didn't find a balance in the ensemble. Neither the performance nor the character were blamed, however.

Laurence Fishburne - CSI: Crime Scene Investigation

Laurence Fishburne

There's no doubt that Laurence Fishburne was one of the biggest names to join the cast of CSI. The acclaimed actor of the stage and screen joined the show in season nine as Raymond Langston, and he served as a main character on the show until season eleven. It was ultimately Fishburne who made the decision to leave the program. He wanted to continue working on both the stage and the silver screen, and he left the world of TV behind.

Ted Danson - CSI: Crime Scene Investigation

Ted Danson

Likewise, Ted Danson also became one of the biggest names to join the ensemble of CSI. The television/film actor joined the CBS series in Season 12, shortly after Laurence Fishburne left, in the role of D.B. Russell and he remained a fixture on CSI until the series finale. Danson stayed on the ship until its final docket, even though the actor was only a fixture for CSI's few remaining seasons. Nowadays, Ted Danson is seen on NBC's The Good Place. Before that, though, Ted Danson opted to reprise his role of D.B. Russell inside the second season of the short-lived CBS spin-off series, CSI: Cyber.

Elisabeth Shue - CSI: Crime Scene Investigation

Elisabeth Shue

Another one of the big names who entered CSI later in the game is Elisabeth Shue, who played the part of Morgan Brody. The acclaimed actress was a main character on CSI starting in Season 12, but she didn't stay on CSI for long. The film/TV actress opted not to return for the show's following seasons, though that was not a concern since the show wasn't picked up for a 16th season. Nevertheless, Elisabeth Shue was nowhere to be found in the feature-length finale, "Immortality." It's not entirely clear why she didn't want to return. Nevertheless, Shue recently starred in Amazon's The Boys.

Elisabeth Harnois - CSI: Crime Scene Investigation

Elisabeth Harnois

Nevertheless, Elizabeth Harnois is an Elisabeth who opted to stick with CSI until the end. The actress first appeared on the CBS drama towards the end of Season 11 in the role of Morgan Brody. But starting in Season 12, Harnois became a series regular and remained one until the big series finale.

The details pertaining to everyone's exit aren't entirely known. There might be some extra that might provide more clarity to everyone's respective exit from the show, in addition to the information we already know. Nevertheless, while there are many actors who opted not to stay on CSI for its entire run, there were several actors who ultimately stuck with it until the end — even if they weren't there from the beginning.
