Jessica Alba and her comic book costars headed to Australia to promote Fantastic Four: The Rise of the Silver Surfer this week. They first stopped off at Fox Studios for a 20 minute preview of the unfinished film and then headed over to Will and Toby's for an after-party. Jessica managed to get in a wardrobe change in between the two events and looks fabulous in both of them of course! In the sequel the four go up against a surfboard riding entity that destroys planets in 8 days. It sounds kind of silly but you know, in that cool comic book way. To check out more about the film and the trailer just click here. It opens in the states on June 15th so hopefully they finish it soon!
