I read somewhere about Disney being water tight on requirements for them to do the press junket and stuff. As you say, if he was going to be a problem they'd probably just axe him from the process anyway. Honestly though, does Bautista have enough of a rep for acting that it wouldn't just make studios not want to deal with him for those antics?
It also does put the rest of the cast in a bad position, I think.
For the GotG fans, is Drax that important to you?
