Loved the old cartoon, Gambit was my favourite so it's always been a bit rubbish he's never made the jump to live action. They even had Channing Tatum attached to play the role only for it to all collapse.
Channing Tatum to me always felt not a great fit for Gambit. A bit too all American captain of the football team, a big traditional jock so to speak, where as gambit is a trickster, a charmer, a thief, a bit sleazy. Physically I always picture him as a bit thinner in build comparatively.
If I had to pick an actor on looks alone for him I would say someone like Austin Butler. Of course whoever would play a Gambit would need a deep Cajun accent.
Channing felt more fitting for a cyclops of anyone.
Absolutely love Gambit in the old cartoon, and as a character in general
