[[wysiwyg_imageupload:9907:]]Bryan Singer tweeted a new image from X-Men: Days Of Future Past where it literally looks as if Mystique has a leg up on someone.
We've previously seen Mystique use her legs in combat, so this wouldn't be the first time.
Any chance the leg belongs to Rebecca Romijn?
Jennifer Lawrence plays Mystique in the movie and judging from the curtains it seems to be set in the 70s, but Singer did just state part of the film takes place ten years after X-Men: The Last Stand, which did feature Rebecca Romijn.
In addition, Romijn did have a cameo in X-Men: First Class.
Following the tweeted image below you can also check out a Jennifer Lawrence X-Men: Days Of Future Past set pic.
X-Men: Days of Future Past has a May 23, 2014 release date starring Jennifer Lawrence, James McAvoy, Michael Fassbender, Nicholas Hoult, Anna Paquin, Ellen Page, ShawnAshmore, with Hugh Jackman reprising as Wolverine, and returning cast members Patrick Stewart and Ian McKellan.
