While all indications are that Deadpool 3 will continue filming despite the writers' strike, star Ryan Reynolds will not be allowed to improvise any scenes because of said writers' strike.
Reynolds reportedly will not be legally able to make quips of his thinking while filming Deadpool 3. In other words, he'll have to stick to the script when he's playing the merc with the mouth, which will probably be an issue for him and the film itself, knowing how Deadpool established himself due in part because of Reynolds' improvised one-liners.
Collider gave the full details of what Reynolds can't do on the Deadpool 3 set during the strike. "Due to the contract writers for the project have with the studio, Ryan Reynolds is not allowed to improvise any lines during the entire time production takes place while the strike isn't over. As they have to follow to the letter the script that was delivered before the conflict began, Reynolds will have to keep any joke he thinks of to himself, completely adhering to what's already on the page." They then added how this could be a problem for the franchise's upcoming installment. "Given how one of Deadpool's most relevant traits is constantly quipping about what's happening around him, it might be difficult for the team behind the movie to have only one option of dialogue for him to say."
This could all change if the writers' strike gets resolved while Deadpool 3 is still filming, but there is no timetable for when that will be resolved. The last writers' strike lasted from November 2007 to February 2008. There's no telling how different this one will be compared to one from 15 years ago, but there are other elements involved that weren't there before, like the revolution of streaming services like Netflix, among others.
This is likely detrimental to the film because Reynolds was quite good at making timely quips to a superhero movie whose primary appeal is its comedy. Reynolds truly was the perfect casting for the lovably annoying Wade Wilson because his style meshes with Deadpool as a character. Of course, it's not like the comedy depended entirely on Reynolds' improvisations. It's not like it's the end of the world if Reynolds doesn't get to improv, even if it's in his wheelhouse.
There was more substance to Deadpool, even though it was primarily a comedy. It took on serious subjects like Wade coming to grips with his new life as a mutant and trying to stop a mass murderer before he went on his rampage. It was more than another simple superhero movie or even a comedy. While the comedy in Deadpool 3 may suffer from the writers' strike, the story shouldn't be bothered as long as they make it compelling enough. With Hugh Jackman's return as Wolverine, there's a lot of potential there.
Deadpool 3 will premiere in theaters on November 8, 2024.
