A Justice League movie would be a disaster. Everyone not named "Batman," "Superman," or "Wonder Woman" would have their roles filled by third-rate actors to keep the budget under control. Bale would likely decline involvement and have to be recast.
WB's meddling would dumb the League down to street level and clad them in "hip" leather costumes (see the attrcious Smallvile episode--as if that isn't redundant). Few people are qualified to write or direct such a film, and even if such people were involved, they would be crippled by WB interference.
Furthermore, The Flash and Green Lantern are among DC's primary cast of characters. They've been consistently popular since their creation, and the idea that they couldn't support their own films is ridiculous. If Daredevil and Ghost Rider can do it, so can Green Lantern and The Flash.
Well ****ing said.
I'm very, very surprised that WB hasn't gotten their **** together yet and done a GL or FLASH film. Perhaps it is because there aren't enough talented, willing directors able and interested in taking on the property(s) -- they aren't nearly as popular as Batman and Superman, and thus I'm sure a director or writer wouldn't be as familiar with the concept of each as well as one would with Batman and/or Superman. I mean, really, who
doesn't know Batman and Superman's origins?
These films (i.e. GL, FLASH, WW) require a director and/or writer with a vision and talent capable of bringing these heroes to the big screen. They also need to respect the character(s), remain objective and still faithful without screwing up the core epicenter of each character's mythology (remaining true to the spirit of the character, etc etc). Which is going to be hard to find for these characters, like I said, because they haven't had the media exposure that Batman and Superman have had -- GL especially, who hasn't had a film yet nor a cartoon or a television series -- FLASH and WW have more clout in that regard because both have had more media exposure i.e. television shows and such.
GL has not, and thus only real comic-book fans would really understand and recongize the merits of a GL film and how to pull it off, and let's face it, there aren't many diehard, sincere, reverent comic-book fan directors out there who aren't hacks or David Goyer. The best directors who've adapted comic-books into films have, for the most part, beeen filmmakers largely disassociated with comic-books themselves (i.e. Chris Nolan, Bryan Singer, Tim Burton, Richard Donner, etc etc). Sam Raimi being an obvious exception.
I'd say give it time. Let WB
try and find the right guys for these jobs. Joss Whedon and David Goyer obviously weren't, or they just weren't at the right spot at the right time. But this isn't Batman or Superman -- a very good reason why we got amazing films is because we had directors like Nolan and Singer APPROACH Warner Bros. about doing a film, which happened to be damn good, and WB had the balls, finally, to listen. Unless we have another Nolan or Singer approach WB about doing GL, Flash, or WW, count out these superheroes on the big screen for the time being.
Sucks, but that's life.
