Next film by Donnie Darko director

Richard Kelly, the writer and director of Donnie Darko, has written and is planning to direct a comedy-musical-science fiction-thriller. I have no idea what that means. Anyway, I love Darko, so I'm more than willing to give Kelly the benefit of the doubt. Although here's what is being said about a cast:
Seann William Scott is in negotiations to star in the project, set to begin shooting in July. Sarah Michelle Gellar, Jason Lee, Janeane Garofalo, Tim Blake Nelson, Amy Poehler, Kevin Smith and Ali Larter are also in talks to join the cast, the trade paper reported.
