The news recently came out that J.J. Abrams of Star Trek is going to produce Mission: Impossible IV after he directed the third movie. But the start of the production might be delayed because the participants are very busy with their schedules.

Abrams will be responsible for guiding the Star Trek sequel, while Cruise recently committed to an untitled film (formerly called Wichita) for 20th Century Fox that will be directed by James Mangold and co-star Cameron Diaz.
