i still think they could have used Kevin Nash as Sabretooth..
but his knees are totally screwed 

oh.. he's also about 6' 10" tall which suits the character of
Sabretooth
*me mysteriously appears in a puff of smoke*
Just got back from jogging. 
About Sabretooth.... they could have just gotten Tyler Mane to
reprise his role.
Anyway, Gambit is looking good.
