In the age of the internet, movie studios have to be incredibly careful with their scripts. If they don't watch out the pages can appear online before you know it and everybody will know what they're planning. There might be such a thing as too much security, however. Donald Glover is starting work on the upcoming Han Solo movie, but his ability to prepare for the project is being hampered by the fact that the studio won't let him see the script.
It's like an owl flies through your window and gives you a script; that's how quiet and confidential it is.
We're going to ignore Donald Glover's mixing of pop culture metaphors in his statement to Xpose.ie here and focus on the fact that the second standalone Star Wars movie just began filming and one of the key actors has apparently not seen the script for the movie he's in. On the one hand, we can understand that a need for secrecy exists. At the same time, it would seem that eventually, you have to make some allowances for the fact that an actor needs to know what he's going to need to do before he does it.
It has to be said that so far the strategy appears to be working out as hoped. At this point, we know absolutely nothing about the film's specific plot. We know the names of several actors who are in the movie and we know who certain characters are, but exactly how they will all fit together is not clear. There have been no significant rumors to give us any idea what part of Han Solo's life we will be seeing on screen.
The script in question is being written by long time Star Wars scribe Lawrence Kasdan and his son Jon. We know that Donald Glover will be playing Lando Calrissian and we know that Chewbacca will be appearing as well. Finally, there was the recent news that Woody Harrelson has been cast as well. The unofficial word is that Harrelson will be playing Han Solo's mentor, though Lucasfilm has been trying to downplay that side of the news, implying that it may not be accurate. Game of Thrones' Emilia Clarke will also be in the film in an undisclosed role.
It's possible that Donald Glover and the other actors have at least a basic understanding of the story, though it's also possible that they each only have a basic understanding of their own characters. It may be the plan to try to get all of this to come together on the set. Of course, now that filming has begun the number of people actively involved in the making of the Han Solo movie has increased by an order of magnitude. It's going to be nearly impossible to keep all the rumors from getting out from one corner of production or the other. Of course, as long as they're little more than rumor, it will be impossible to tell which are legit and which are not until the movie actually comes out.
