Who co-wrote Dead Reckoning Part One with Christopher McQuarrie?

Christopher McQuarrie co-wrote Mission: Impossible – Dead Reckoning Part One with Erik Jendresen.

Jendresen is an American screenwriter and producer whose credits include the television miniseries Band of Brothers and the film Thirteen Days. His involvement gave the seventh Mission: Impossible film a writing partnership alongside McQuarrie, who also directed it and continued shaping the franchise’s larger story.

The film was originally promoted as Mission: Impossible 7 and later titled Dead Reckoning Part One. It follows Ethan Hunt and his team as they confront the Entity, a powerful artificial intelligence, while rival governments and agents pursue the key that could control it.

A common mix-up is confusing Jendresen with other franchise writers. Josh Appelbaum and André Nemec wrote Ghost Protocol, Robert Towne wrote Mission: Impossible 2, and Drew Pearce was involved with early work on Rogue Nation—not this film’s credited screenplay.
