I had no idea Chris McQuarrie wrote and directed this. He previously worked on the script for Bryan Singer's "Valkyrie" that starred Cruise so there's a little history between the two. I am a little more interested in this than I was before because of this. Plus the TV spots have been pretty decent.
He also did a re-write of the latest Mission: Impossible movie for Cruise, although he didn't end up getting credit. IMDB says he is currently writing the next film in that series, plus the stalled Top Gun 2. Cruise must like him.
