At this point, status updates on Superman: Man of Steel are almost not worth mentioning. Just after the New Year arrived in January, we posted a rumor that filmmaker Bryan Singer might get cut from the upcoming Superman Returns sequel - there seemed to be some inside talk that Singer might be replaced in order to keep the sequel on track. Empire (and IESB) confirm today that Singer is indeed still attached, but the project is still quite a ways out. In fact, it doesn't even have a script yet (still), so as I said at the start, this really isn't going anywhere.
The rumor speculated that the sequel was in such a point of development hell that Singer mind end up just focusing on his other two projects, Valkyrie and The Mayor of Castro Street, instead, and in a desperate attempt to get a sequel made, Warner Brothers would push the project forward without Singer. However, Singer comes in and debunks that rumor straight up, at least as far as we know.
