Anne Thompson's blog has an update on a sequel to Superman Returns. The update is, there really is no update:

The debate continues to rage about what Warner Bros. should do with Superman. The last movie, Bryan Singer's Superman Returns, paid hommage to the Richard Donner Superman movies without completely updating the franchise the way Christopher Nolan did with Batman Begins.

Fans have been clamoring all over the web--and on this blog--for a complete reboot. And within the halls of Warner Bros. the same debate rages on. They too believe that the last movie didn't break the mold and wound up in some kind of middle limbo. Today I was told that it is a priority at the studio to find the right direction and if Bryan Singer is willing to do that, fine, but if he gets in the way, he may not stay on the project. There are no writers working on a Superman script now. The studio wants to figure it out. "It might be better to start from scratch," one exec admitted.
