I think Jim Carrey would make a great Joker!!
Matt Damon- Green Arrow
Michael B Jordan- Green Lantern (Jon Stewart)
Johnny Depp- Riddler
Jonah Hill- Penguin
Zoe Saldana- Catwoman
She’s not famous per se, but Terry Ferrell would’ve made a dynamite Catwoman in the 90’s/00’s.
Great choice on Damon for GA.
I wonder if Rick Baker had Jim Carrey in mind when he designed his Joker bust. You can really see Grinch-style Carrey in the face of that thing.
