Re: Namor the Sub-Mariner
Vin as Namor would be fine, IMO. He's got the build, can act and has a screen presence. Just give him a wig and the Spock ears and eyebrows and it could work. I just hope it's a MCU film because I have zero faith in Universal after the utter failure of Hulk. The only good thing I can say about them is that after making the worst big budget superhero movie of all time they wisely got out of that genre.
There's no such thing as a movie that's too big to fail.
