With five straight Number 1 singles and an upcoming hosting gig on ‘Saturday Night Live,’ Katy Perry is loving life. Movie execs have decided to remix Perry’s new single, ‘The One That Got Away,’ for a new video to promote the film ‘My Week With Marilyn.’

The movie tells the story of the time in 1956 when Marilyn Monroe spent a week in Britain filming a movie without her husband. A young production assistant accompanies the Hollywood star and introduces her to everyday life in England.

The Mike Relm-created remix is paired with video and audio clips from the film showing Marilyn at her most glamorous. ‘My Week With Marilyn’ opens in U.S. theaters this week.
