The Crudup Conundrum

This is sort of a 'non-news-news' type of story. Calls placed into Billy Crudup's publicist and agent were returned with a 'Cannot talk about it, ask the studio', when asked if Crudup will be at Comic-Con we received a 'Cannot talk about it, ask the studio, sorry'. Following this logic can lead us to believe that Crudup may be involved in the film, however with this logic we can also say Charlie Chaplin may be in this film...since no one is saying much. All signs point to at least one major casting announcement at Comic-Con, if not more.
