It's official: the fourth Mission: Impossible movie will be called Mission: Impossible Ghost Protocol, according to Gulf News. The title was revealed at a press conference in Dubai, where the upcoming sequel has just started shooting. Here's what Tom Cruise had to say about this new title:

"One of the things I always wanted for the franchise was for it not to have a number afterwards. I've never done sequels to films and I never thought of these films as sequels. Paramount has done a great job in coming up with a title, so it's not going to be MI2, 3, 4: it's going to be Mission: Impossible Ghost Protocol. I always felt it should have a title."

Producer Jeffrey Chernov then spoke about the advantages of shooting a big-budget action movie in Dubai:

"We sent a lot of advance crew out to figure out how we can rig and shoot and stunt, and they all came back and said Dubai was so advanced, the harnesses were already built in. It is a town that feels like it was meant to be filmed in. Every movie needs a heartbeat, a centrepiece, and the centrepiece of our movie is Dubai."
