Carey Mulligan and Isla Fisher plotted to keep The Great Gatsby costumes

Carey Mulligan hatched a plot with her The Great Gatsby co-star Isla Fisher to steal their elegant costumes from the set of the 1920s movie.

The two actresses were thrilled with the glamorous outfits they were required to wear for Baz Luhrmann's upcoming film, in which they play society women alongside Leonardo DiCaprio in the title role.

The pair even conspired to keep the costumes for their private closets once the cameras stopped running, but their plan was foiled.

Fisher tells British magazine Hello!, "I think we were all so enamoured with the costumes and sets that we wanted to hang around even when we weren't shooting. Carey and I were plotting how to steal our costumes and sneak them off set. Sadly, that didn't work out too well. But they were all great. I had a really great time."
