Between Variety and Deadline Hollywood last week, we found out that Paramount is "rebooting" the Mission: Impossible franchise with the fourth installment. Jeremy Renner has been cast as partner spy agent to Tom Cruise's Ethan Hunt, with an eye toward Renner taking over as the lead in future MI films. Brad Bird is directing, and the word is that the fourth film will not be called "Mission: Impossible 4." Now, Production Weekly has a listing for a film called "Aries (aka Mission: Impossible 4)." Meanwhile, several actresses are being tested for the female lead, according to another Deadline Hollywood post. The film will open in December of 2011.
