In my own personal opinion, I think that Sylvestor Stalone could pull off the part of the JLA's reluctant leader, he might need to alter his voice and demeanor, he'd be like "Yo' Batman" in the trite "Yo' Adrien" style.
Bruce Wayne and David Duchovny look alot alike in my opinion, and Duchovny can pull off that "Shut up, I'm thinking!!" look really well. He might need a little martial arts training and some body armor (ala the original Batman movie) and you'd have Batman.
Besides the fact that she's one of the only actresses that looks like Diana, Elizebeth Hurly could more than likely pull of a physical roll like that of Wonder Woman.
Mabye throw in a little red hair dye and a cool costume and David Chokachi could become the Fastest Man alive in no time flat.
Matt Leblanc looks alot like Kyle Rayner and that and some good acting would earn him his check as the Emerald Knight.
In the movie Waterworld, Kevin Costner played a character very much like this, minus the hook for a hand of course, but give him one and he could play a good king.
Slap some gray paint on Casper Van Dien here and give him a flaming sword and you'd have Luthor and his cronies soiling their collective underpants!!!
Micheal Dorn already plays the Klingon Worf on Star Trek: Deep space 9, and Star Trek: TNG. All you would need is some green paint and a forehead protrusion and you'd have Martian Manhunter. Dorn has a cool voice and demmeanor, and plus he is used to wearing things on his forehead.
I don't think Steel should be in the JLA if he's going to be played by Shaquille O'neal. So if he's going to be there he needs to be played by a TALENTED actor (Unlike Shaquille) like Micheal Jai White.
Besides looking like Eel O'Brian, Jim Carey with the help of some special effects could play the lackluster character (Lackluster is a nice was of saying "Plastic man is a piece of dog fecies") Plastic Man.
Besides looking like the Huntress, Charisma Carpenter could do a nice job bringing the Huntress to life on the screen, plus she could pull off the physical requirments.
For the badass of the movie I go to Prometheus (who might I add in the articles I read Grant Morrison said that Prometheus was going to take down the ENTIRE JLA. He didn't take down Superman, Wonder woman, Aquaman or Oracle. Greatest JLA villan my ass, could have got Despero down there to finish the job. But thats not Prometheus's fault, I won't mention any names, Grant Morrison:loser) But anyway, I'll take Rutger Hauer for Prometheus.
Favorite Hanson Member: None
Assistant Director: Me
Least Favorite Member of Hanson: All of the Above.
Security on the set: NwO the white and the black, none of that Wolfpac crap.
Torture victim: Sean "Puffy" Combs, like after a hard day of filming you could just go out back and shove bamboo under Puff Daddy's fingernails. Or you could cut off his ear and then pour gasoline on him all the while singing " Got clowns to the left of me, Jokers to the right, here I am Stuck in the middle with you" and then you could start calling yourself Mr. Blonde and then you could be killed by a guy calling himself Mr. Orange. that was fun.
