"I heard from a pretty reliable source this weekend – who, has some top contacts himself – who essentially confirmed that the WB are thinking of putting the next “Superman” movie into turnaround, and instead will just use the character in the new “Justice League” movie. (Funnily enough, Batman would not be involved in the new film – he’s too big to waste on a film like this, apparently).
Having now heard the same from about half-a-dozen reliable insiders, I checked in with a couple of sources near the Water Tower itself, who wouldn’t confirm nor deny the reports, but definitely haven’t dismissed that it’s a possibility. One of them would only say that there “could be something in [that]”
If true, that's quite interesting. The evidence would also seemingly be starting to mount against Singer getting the chance to have another go at the rotting corpse of Superman he left us or at the very least delaying it.
It seems they'd be taking Superman for the JLA film as a way to help try to drum up support for the Superman character after the lackluster box office from the first Singerman film. If the JLA film was a monster hit, the article muses, they might then go ahead with a Singerman 2. But does that make much sense? If someone is able to make the JLA a monster hit using Superman (hopefully, correctly this time) why would W.B. then want to turn around and hand him back to the guy who screwed it up the 1st time? Unless of course they mean, they'll go ahead with another Superman film perhaps not with Singer attached to direct again, but that's not really clear.
The article also states that they think Brandon Routh would most likely be donning the tights again in the JLA film, but I'm not too sure about that. If you believe some of the rumored script ideas for the JLA movie Routh's Superman wouldn't exactly be in continuity with it, although let's face it his Superman wasn't in continuity with ANYTHING. Another thing to consider is that he might have the stigma of being part of Singerman attached to him, and if WB's unhappy enough with the Singerman franchise to bale on it, or at the very least delay it for a while, why would they want to risk the public associating the two films by having the same star in the same role?
UPDATE: IGN has admitted hearing the same rumor over the weekend.
