Back in February, after six months of shooting and with only a few weeks left on the schedule, director Christopher McQuarrie decided to stop filming to redo the ending. Don't they ... usually have that all figured out before they put the actors in front of the cameras? Yeah, but in this case McQuarrie suddenly decided he wasn't satisfied with what appeared in the script -- a script that had gone through three writers, including the guy responsible for classics like Call Of Duty: Modern Warfare 3, Need For Speed: Rivals, and no movies whatsoever. It's worth noting that this writer's hiring was announced with great fanfare last year, and yet McQuarrie himself is the only one listed in the writing credits now.
So if your life's goal was to never see Alec Baldwin again, you know exactly who to blame.
And so, in a race against time worthy of its own action movie, production was shut down for a week while McQuarrie and a mysterious unnamed co-writer friend hammered out a new finale, presumably after this friend read the script and described it as, "... Great, really."
An anonymous Paramount insider downplayed the shenanigans, saying, "Chris, Tom, and a third person wanted to take a minute to get from what they thought was a good place to a more perfect place," which doesn't instill as much confidence as they think. "A minute"? We gave more thought to planning our high school projects, and we didn't even have $150 million to buy poster board.
