"This is what I was told by a WB source (exec), Welling is going to Supes, I asked if this was 100% and I was told that yes. Last week I was told that something went awry with Welling. I don't know if that has anything do with Gough and Millar not being part of the production or if it was money.
I keep being told that one of the biggest problems that WB is having and something that they don't want to deal with is that the studio does not want to have three Supermans, Routh, Welling and new guy.
Some people at WB think that if Routh is brought back for Justice League it will help reinvigorate the solo franchise. A year later after the release of JL, Singer could come back and do his Man of Steel.
Will that happen? Don't know but I did hear that Routh had a meeting with Dan Lin, I don't know what the results of the meeting was.
Can Welling still be cast for Supes? I was told that it is up to his camp."
