Did anyone else know the legendary Burj Khalifa climb in Mission: Impossible: Ghost Protocol was basically improvised? Apparently, Tom Cruise realized the scene wasn’t working and secretly brought in Christopher McQuarrie to write it on the spot—without telling the director or Simon Pegg! McQuarrie came up with the now-iconic 'blue is glue, red is dead' line and totally saved the day. This twist totally changed the franchise’s direction and Cruise/McQ’s partnership.
