Tom Cruise returns as Ethan Hunt in the fourth installment of the Mission: Impossible franchise. Ghost Protocol is directed by Brad Bird (The Incredibles). Ving Rhames and Simon Pegg reprise as Luther Stickell and Benji Dunn, respectively, and Jeremy Renner, Josh Holloway (Lost‘s Sawyer), Anil Kapoor, Paula Patton, Vladimir Mashkov, Michael Nyqvist, and Lea Seydoux join the cast. M:I 4 is a Bad Robot Production; J.J. Abrams produced the film (with Cruise and Paula Wagner) and co-wrote it with André Nemec and Josh Appelbaum (these guys previously worked with Abrams on Alias).

Here’s a synopsis that’s making rounds across the ‘Net: This is not just another mission. The IMF is shut down when it’s implicated in a global terrorist bombing plot. Ghost Protocol is initiated and Ethan Hunt and his rogue new team must go undercover to clear their organization’s name. No help, no contact, off the grid. You have never seen a mission grittier and more intense than this.

The trailer, in a word, is awesomesauce. It’s action-packed, thrilling, and sexy–a great mix if you ask me. And how insane is that final sequence we’re left with? Cruise actually scaled Dubai’s Burj Khalifa, the world’s tallest building, to get the shot. Plus the theme song, it never gets old.

Mission: Impossible – Ghost Protocol hits standard and IMAX theatres on December 16, 2011.
