During Paramount’s CinemaCon presentation earlier this year, it seems that Tom Cruise mentioned Christopher McQuarrie appearing on the set of Mission: Impossible – Ghost Protocol while they were struggling with a particularly complex scene, which he referred to as a “Rubik’s cube.” Interestingly, at the time, Christopher McQuarrie wasn’t directing the movie; Brad Bird was. Moreover, McQuarrie wasn’t officially credited as a writer for the film. However, Cruise managed to bring him aboard even before they had received formal approval for his involvement.
