Re: Who should play Thanos?
Perlman would be good, no doubt. I guess my thought with Diesel is that he has the deep voice and the size to pull off an imposing Thanos. Although, yeah, I'm not sure he has the range. Though I've never found Thanos to be particularly smart; he's just so powerful that no one dares challenge him. But he's definitely batsh** crazy, and whoever plays the role has to be able to display that. Not sure if Vin can.
But if it keeps him from making more Riddick movies, then I hope it happens.
Casting for Marvel's NETFLIX shows:
