Lily James on Buffing Up to Kick Zombie Butt – and That Time She Accidentally Stepped on an Extra's Head

Lily James is back in a corset this week, nearly a year after her breakout role in Disney’s Cinderella had a very happy ending as it became one of 2015’s biggest hits. This time, though, she’s packing some serious weaponry inside that garment.

The beautiful 26-year-old Brit is Elizabeth Bennett: Undead Hunter in Pride and Prejudice and Zombies, the big-screen adaptation of Seth Grahame-Smith’s best-selling 2009 literary mashup. In the film, like in the novel, the highly trained Bennett sisters are on the frontlines of early 19th century Britain’s bloody battle against invading zombies (while of course, also finding some time for love and marriage, with another Disney live-action alum, Maleficent star Sam Riley, playing reluctant suitor Mr. Darcy).

James, who also plays Lady Rose Aldridge in TV’s popular period drama Downton Abbey, told us she had to get out of “tea and biscuit” mode to prepare to fight for her life in PPZ. Now, though, she has clearly caught the action bug. In fact she may have been just a little too eager to put the hurting on walkers at points. Just ask the extra whose head she “properly kicked in” (by accident) while filming. Read on for the full story.
