These are things I learned from watching G4's Attack Of The Show today:
Karen Allen, Marion Ravenwood from Raiders of the Lost Ark, is a confirmed member of the Indiana Jones 4 cast, and she is indeed playing mother to Indy’s greaser son, played by Shia Labeouf (with a beard).
300 director Zach Snyder is adapting comic book epic Watchmen, and he has revealed the main cast members. They include Billy Crudup [Almost Famous] as Dr. Manhattan, Jackie Earle Haley [Little Children] as Rorschach, Matthew Goode [Match Point] as Ozymandias, Patrick Wilson [Hard Candy] as The Night Owl, Jeffrey Dean Morgan [TV's Grey's Anatomy] as The Comedian, and Malin Akerman [Harold & Kumar]as Silk Spectre.
Zachary Quinto, Sylar on Heroes, is now confirmed as Spock in J.J. Abrams’ Star Trek prequel. Leonard Nimoy will also reprise his role, as old Spock, I guess; Shatner is rumored to be joining up.
Oscar-winning Tsotsi director Gavin Hood is set to direct the Wolverine solo flick.
Harold Perrineau will return as Michael Dawson, Walt’s father on Lost.
Kevin Spacey has expressed commitment to a Superman sequel.
According to frequent collaborator, actress Rosario Dawson, Sin City/Grindhouse director Robert Rodriguez is going to remake Barbarella.
Knocked Up star Seth Rogen will adapt The Green Hornet with his Superbad writing partner Evan Goldberg. It is still unknown whether he will star in the title role, but he has announced his desire to cast Kung-Fu Hustle star/director Stephen Chow as The Hornet’s sidekick, Kato.
And G4 had their own announcement: they will air the Spaceballs animated series this fall.
