'My Week With Marilyn' Katy Perry Mash-Up: One Which Got Away? (VIDEO)

.publish-content img As it is Friday, here's the Katy Perry/'My Week With Marilyn' mash-up you bought. After Perry opened up the extended version of her video for "One Which Got Away" with advanced tests of 'My Week With Marilyn' the other day, The Weinstein Company has revealed a completely new video that mixes clips from 'Marilyn' with Perry's latest single in the apparently bottomless album, 'Teenage Dream.' The finish result? Well, just like a Katy Perry devotee, it's not nearly as good since the actual version of "One Which Got Away" -- nor its video with Diego Luna and Katy Perry in old-lady make-up -- nevertheless it does feature Dominic Cooper and Derek Jacobi. So, draw? Watch above. 'My Week With Marilyn' is going in theaters on November. 23. Follow Moviefone on Twitter Like Moviefone on Facebook
