Ethan Hunt has taken on some of the world’s most dangerous villains in a series of deadly missions. But his latest mission may have been just too impossible for him. Impossible enough that it required some rewriting.

EW has confirmed that production on Mission: Impossible 5 halted for one week so that the ending to the film could be reworked. The production, which is shooting in London, has now resumed and is currently in the process of filming the revised ending.

(The Hollywood Reporter originally reported that director Christopher McQuarrie, Tom Cruise, and a third, unidentified writer took a week to improve the ending.)

Mission: Impossible 5 was moved up to a July 31 release from its originally planed debut in December in January and is still expected to release in that summer slot, with the short hiatus not intended to impact the rest of the film’s production.

Mission: Impossible — Ghost Protocol, the last film in the franchise, released in 2011 and set new box office records for the series. That film also tasked series star Tom Cruise with scaling the world’s tallest building, so finding a way to top sequences like that, the film’s finale, and whatever ridiculous action the similarly timed Furious 7 has planned is surely no easy task.

Another prominent Paramount action film, World War Z, went through some major third-act rewrites—though The Hollywood Reporter‘s story states that Mission: Impossible 5‘s script alterations are reportedly not meant to be as extensive, with Paramount reportedly only wanting to perfect what was considered a good ending by the studio.
