Don't hold your breath for that Justice League of America movie. Today was the deadline for Warner Bros. to decide whether to green-light production or put the film on the backburner until script revisions could be done. The studio has reportedly opted to do the latter.

Variety got the official word from Warners that JLA has been put on indefinite hold until after the ongoing writers' strike is resolved, which is anyone's guess (especially if the directors and actors' guilds go on strike this summer). Rather than starting filming this spring as expected, JLA won't likely go before cameras until late summer or the fall.The trade reports, "Castmembers were informed late Tuesday that their options would not be exercised, but they were also told that the studio is determined to make the film, with them in it. Unfortunately, there were insurmountable problems that made a delay the best option. The studio's reasons included not getting the official response it needed on tax breaks from shooting in Australia. And while WB execs like the script they got from Kieran and Michele Mulroney, it would benefit from a little more work, something that isn't possible because of the writer's strike."Variety confirms that Adam Brody was set to play the Flash, Armie Hammer Jr. was going to be Batman, and Megan Gale was to play Wonder Woman. Although their options lapsed, the trade says the studio still hopes and expects to make the film with them later this year -- provided they aren't booked for other jobs in the meantime.UPDATED, 1/17: The Hollywood Reporter now confirms that Common, Anton Yelchin, D.J. Cotrona, and Teresa Palmer had also been cast in the movie.
