I still think Jason Momoa is gonna steal the show on this one. He looks like he's just having so much fun.
Every scene he's laughing or making jokes. He will definitely be good. I think WW will be good in it too though.
Though, what's up with casting dudes with dark hair to play Barry Allen? He was a blond in the comics.
I was surprised about that too. Then again, they cast Jason Momoa as this guy:
So I'm guessing that they're trying to go by the actor's ability to fit the role, and not just physical characteristics. Hopefully that will pay off! Personally, I'm already liking this version of the Flash.
People aren't really following the characters perfectly in the comic book movies(and shows) of late, but I normally don't mind, as long as they portray the character well. Also, there are times of versions of characters, especially Aquaman.
