I am not familiar with movie actors, and I certainly have never heard of any of the people that you mentioned. The only role that I would have any clue for casting would be Xavier Latour, and I would cast Bobby Lashley in that role.

Though he's most famous for pro wrestling, Bobby Lashley's been in MMA and has had a few acting roles, so I feel that the combination of size, speed, strength, and previous relevant experience make him a good fit here.

I've resteemed the post in the hopes that maybe other people can come up with some good fits for the other roles.
