Sandra Bullock Plugs "Gravity" at Comic-Con 2013

Sandra Bullock Plugs

Hoping to create buzz for her new film, Sandra Bullock headed to Comic-Con 2013 for a signing for “Gravity” at the Warner Bros. booth on Saturday (July 20).

The “Heat” star looked pretty in red as she happily signed photos for fans at the San Diego Convention Center.

Unfortunately for female fans, her sexy co-star George Clooney was noticeably absent from the event.

In the flick, astronauts attempt to return to Earth after debris crashes into their space shuttle, leaving them drifting alone in orbit. “Gravity” hits theaters on October 4th.
