Will We Ever See Sherlock Season 5? Here's What We Know

Sherlock Season 5 has remained unannounced, but not undiscussed, so now we have to discuss it. 

There was a time when Sherlock was on top of the world. Regarding the most interesting Sherlock TV shows or movies, the U.K. series, starring Benedict Cumberbatch and Martin Freeman, was one of the best. 

However, it's been a decent amount of time since the last season of Sherlock was released. Season 4, which came out in 2017, has long been seen as the show's conclusion, but the thing is that Sherlock was never canceled. There was never an announcement that the show was ending or even the creators coming out saying that the series was coming to a close. There are reasons – and if you’re wondering if a Sherlock Season 5 might happen, here is what’s been said.

Steven Moffat Says He Would Start "Writing Tomorrow" If Cumberbatch And Freeman Came Back

The first thing we have to talk about is that Steven Moffat, the co-creator of Sherlock, has openly said that he would start "writing today" if both Benedict Cumberbatch and Martin Freeman wanted to return to their roles in the show. 

In an interview that Moffat did with BBC Today (via The Independent) in January 2023, he said that he would begin working on Season 5 if the two main actors were able to return to the roles despite their hectic schedules: 

Look, I'll start writing Sherlock tomorrow if Benedict and Martin will show up, frankly.

Moffat then jokingly added that because the two actors have moved onto "bigger and better things," the rest of the Sherlock crew had been left behind:

Sadly, they've moved on to bigger and better things and left us behind, crying. But Benedict, Martin – please come back?

Either way, it's already clear that Moffat wouldn't mind working on another season with the two of them if they were to return. But there's also an interesting key piece of news about Sherlock Season 5 that we should discuss – one from years ago. 

That’s not even taking into account that there are plenty of other actors who could come back too. For a refresher, here is who is a part of the main cast of Sherlock:

With so many main characters, one can only wonder if all of them would return for a Season 5.

Moffat Also Planned Season 5 With Season 4 Years Ago, So The Ideas Are There

In 2014, Steven Moffat said that Season 5 was planned out simultaneously with Season 4. At a BAFTA screening for the Season 3 finale, "His Last Vow" (via The Independent), he revealed that both he and Mark Gatiss, the other creator, had worked on both series (seasons) 4 and 5 for the show:

Rather excitingly, Mark (Gatiss) and I, for no particular reason, just started plotting out what we could do in the future. We plotted out the whole of series four and five. The ideas we had that day, I thought, were the best we've ever had. So we have got plans – but our plans don't tend to be 'Let's blow up the world or cast the most famous person in the world', they tend to be 'What exciting twists and turns can we add to this?' and I think we've got some crackers!

Hearing this is major because the fifth season hasn't even been announced – and it's even more surprising that they planned both but only ended up going with Season 4.

Benedict Cumberbatch Has Said "Never Say Never" To A Possible Season 5

However, even if Sherlock Season 5 is still up in the air, the show's main star did once say that it's possible he could return. 

How Doctor Strange Affected Benedict Cumberbatch During Sherlock Season 4

Benedict Cumberbatch, who won a Primetime Emmy for playing Sherlock Holmes, said in an interview with Esquire in November 2021 that he says "never say never" to returning to Sherlock for a fifth season. The circumstances "need to be right" for him to come back:

Oh look, I still say never say never. You know, I really like that character… it's just, the circumstances need to be right and I think maybe it's too soon now to see it have another life. I think, wonderful as it is, it's had its moment for now. But that's not to say it wouldn't have another iteration in the future.

Cumberbatch even confirmed this earlier on in an interview with Collider in May 2021, saying that “if the script’s right,” he would return to the role, so it’s clear he’d be open to coming back. He even said he’d be willing to do it if it was a film and not another season – which we’ll get into in a bit. 

Benedict Cumberbatch has been extremely busy since Sherlock ended its fourth season in 2017. Not only has he taken on the role of Doctor Strange in the Marvel Cinematic Universe ( playing the sorcerer in 2022’s Doctor Strange in the Multiverse of Madness), but Cumberbatch has done so many other great movies since.  Even in 2023, he was a part of several other films, as well as a series of Wes Anderson shorts, called The Wonderful World of Henry Sugar. 

However, hearing Cumberbatch say he's willing to return under the right circumstances should be great for fans.

Martin Freeman Is Also Game For A Fifth Season If There's A "Good Script"

You can't have Sherlock without Watson. In any iteration of the famous franchise, Watson is always there to help the man, and Martin Freeman was the perfect casting to go with Benedict Cumberbatch. The good thing is that Freeman says he would return to – provided there was a "good script."

In an interview that Freeman did on The Jonathan Ross Show in November 2022, he revealed that the "door is never shut" on Season 5 of Sherlock, and that he would come back if there were a good story for them to tell: 

I don't know. Personally, I'm a fan of things being finite. I like things ending. I think it's natural for things to end…but I'm also a sucker for a good idea and a good script. If something comes up that persuades us all – it would have to be us all – then my door would always be open.

Martin Freeman has also been recently successful over the last few years. He too joined the MCU to play Everett Ross, and he's appeared in many other movies and shows, including A Christmas Carol, The Operative, Ode to Joy, and the TV shows Angelyne and Breeders, so he's been quite busy. He even co-starred in Miller's Girl with Jenna Ortega in 2024. 

Freeman also revealed that he was happy to be "taking a break" from Sherlock back in 2018 when the show first went on hiatus, but hearing the two stars talk so freely about possibly coming back to the series is optimistic.

Sherlock Season 5 Could Also Become A Movie

The last thing we should mention is that Sherlock Season 5 could become a movie if given the opportunity. 

In an interview that Mark Gatiss did with The Guardian in July 2023, he was asked why he likes to turn big IPs like Sherlock and Dracula into miniseries rather than films. 

Gatiss said that he was genuinely interested in making them for TV and that it's hard to get people interested in cinema. Adding that on, he also said he would "love" to make a Sherlock movie: 

People think you can just wave a wand. It's incredibly difficult to get people interested and get films made. I remember talking to Edgar Wright about Ant-Man, into which he put eight years of his life and then didn't make. Eight years is not short of a decade. Add a few of those up, you're dead and you've made four films. But, also, we were genuinely interested in making them for T.V. because we love T.V. We would love to make a Sherlock movie. It's the natural thing to do.

While this doesn't confirm that he would do that, it's also a great thing to bring up,] considering I have seen plenty of miniseries and shows go that route, where they make a movie after several years. Sherlock could end up following that path.

And realistically, that might better fit into Cumberbatch and Freeman's busy schedules compared to a multi-episode series, where every episode is decently long. Who knows? 

This was even further confirmed in an interview with Deadline in April 2024, where Gatiss continued to say that he’d love to make a film to continue the story, but the process of getting “everyone together” is rather “difficult” with the actor’s schedules, and referencing the Ant-Man process yet again: 

We’d like to make a film but trying to get everyone together is very difficult…you’ll have to ask Benedict [Cumberbatch] and Martin [Freeman]...people think you can just wave a wand. It’s incredibly difficult to get people interested and get films made. I remember talking to Edgar Wright about Ant-Man, into which he put eight years of his life and then didn’t make it. Eight years is not short of a decade.

The fact that it’s still at least in the conversation is a good thing, but I can understand if we have to wait some time for the conclusion, especially if it's a film. 

Either way, Sherlock Season 5 still isn't confirmed, and we'll likely have to wait for news for a while, if ever. But until then, I'll rewatch the show and be sad that I'm still waiting – or maybe check out the Robert Downey Jr. Sherlock movies again because I'm craving my mystery flicks.
