I'm just curious as to why would Will Smith take up a role knowing that it might end up being a reoccurring role but says he doesn't want to do sequels or play a role twice?

I just rather his ass just stick to not doing superhero movies at all, I was kind of surprised he did three Men In Black movies, then says "I'm done with doing roles more than once" schtick, I wonder who they will get to play Deadshot now?
