not like they have a choice. Unlike Deadpool, who's origins began well into adulthood, Gambit's active origins started in his teens. Just not going to work unless they want half the movie to be played with different actors. Tatum and anyone around him (Julien, Bella, assuming there will be anything shot in NOLA) probably arent going to look youthful enough to be believably in their late teens or early 20s. The more time this takes (the older Tatum gets), the less likely it'll be an origins, which imo is a good thing. It also makes it less likely he'll be joining up with the current crop of younger X-Men, making it way more likely for his movie to take place in the same timeline as Deadpool and possibly New Mutants (no way New Mutants takes place in the current X-Men timeline, that being the 80s-90s).
