Christopher McQuarrie, the man behind the successful “Mission Impossible: Rogue Nation,” looks like he’s on high demand in Hollywood these days as a script doctor. He was brought in to polish the script of “Rogue One: A Star Wars Story.”

A story that originally appeared in the Latino Review and was later confirmed by Birthmoviesdeath, states that McQuarrie was asked to fix the script of the highly anticipated “Rogue One.” The writer/director did a two-week pass on the movie’s script.

Gareth Edwards’ “Rogue One: A Star Wars Story” was originally conceptualized and written by one of the inventors of Photoshop – John Knoll, now the chief creative officer at Industrial Light & Magic (ILM). Knoll is also the visual effects supervisor of “Rogue One.”

Knoll’s treatment was then converted into script form by Gary Whitta. After Whitta left the project for “Starlight,” Chris Weitz picked it up. However, even after all those re-writes, the script for “Rogue One” wasn’t up to the mark. This was when McQuarrie was brought in by Lucasfilm, which has been acquired by Disney from George Lucas.

It must be mentioned that McQuarrie has been previously called to fix the script of “World War Z” when the movie went over its budget and Paramount Studios had to reshoot the third act.

McQuarrie is best known for being the Oscar-winning screenwriter for Bryan Singer’s “The Usual Suspects” and the director of hit movies like “Jack Reacher.” He also wrote the screenplay for director Doug Liman’s “Edge of Tomorrow.”

McQuarrie reportedly came in fairly early during the shooting of “Rogue One” and used his skills in writing other successful heist stories like “Mission Impossible” to tighten the story of the first “Star Wars” Anthology movie.

Birthmoviesdeath writer Devin Faraci added that it is unlikely that McQuarrie will receive credit on the movie despite having “saved” the script, which could otherwise have been a disaster for Disney and Lucasfilm.

“Rogue One: A Star Wars Story” will hit cinemas worldwide in December this year.
