...and Batman can still beat him up.
Duh. Batman beats everybody.
No idea. As long as it isn't Timberlake.
Christian Bale wouldn't be bad, but that'd be ... awkward. Especially when they film the JLA movie.
They could do John Stewart as GL and have Laurence Fishburne act. But Stewart as GL wouldn't be 'classic'.
Probably just gonna be a stupid mostly-origins movie anyway grumble grumble grumble
