It's the cast of Fast & Furious! I went to the London premiere, everyone came in to introduce the film except for VIn Diesel, cuz he had to do a talkshow. The film is TERRIBLE BTW. Michelle Rodriguez did a whole speech about how she was only back because the formula was right and blah blah, and she's only in 1 scene. lol. Paul Walker apparently has some rivalry going with Vin Diesel about who is the better driver. Paul was HOT.
