There's a possibility Bryan Singer may not direct the remake of Logan's Run.

Variety reports Warner Bros. and producer Joel Silver want to start shooting the sci-fi pic this fall. That would mean Singer might end up shooting the two films, Logan's Run and a Superman Returns sequel back-to-back. Assuming Superman Returns is a hit at the box office, Warner plans to start shooting the sequel in the later part of 2007, with Singer again as director.

Even if he doesn't direct Logan's Run, Singer is still likely to play some sort of role and perhaps take a producer's credit. An official decision either way won't be made until Superman Returns opens on June 30th.
