I hate any of the "he/she stole the show" because it is highly subjective and it depends on how much you like that certain actor.
Really? I must have been watching ANOTHER Gambit.
...he more or less stole Wolverine away from Hugh Jackman with his charismatic turn as Gambit.
I like Taylor Kitsch but the fact that his carreer burnt down as quickly as it started sort of proves that he is not up to steal anything from anybody. However, I have to admit that when you are in two big blockbuster flops, it is easy to blame it on the main actor...
