James Gunn's DC Universe will inevitably introduce a new Justice League, and there are a few actors that would be perfect for the team.
Superman will be an unknown Christopher Reeve / Henry Cavil type
Batman another A lister like Affleck
WonderWoman a 6ft unknown (like Gadot pretty much was)
My picks would include:
JUSTICE LEAGUE -
Superman: David Corenswet (locked in now)
Batman: Oliver Jackson-Cohen
Wonder Woman: Jessica Green
Flash: Glen Powell
Aquaman: Mason Gooding
Green Lantern (Hal Jordan/John Stewart): Austin Butler/LaKeith Stanfield
Martian Manhunter: Doug Jones
