Kinda OT but I find funny how many Americans have never heard a Cajun accent before. I'm aware that US is the size of a whole continent, but still. So many people laughing at Tatum's accent without realising they were unintentionally insulting a lot of Cajuns who keep claiming "...but we do sound like this!" There is a lot to criticise Tatum for, but I keep reading that the accent was on point. And Gambit probably was a more thicker accent bc his family are all old people.
Little Trivia, in the Spanish dub of the movie, the accent is generic french. In the og cartoon, they called him french too, not Cajun and he has no accent.
