London: Actress Helena Bonham Carter who filmed elaborate action sequences for the upcoming `Harry Potter` film says that the exercise left her "crippled" and in terrible pain.
The 45-year-old actress, who plays evil witch Bellatrix Lestrange shot a sword battle with Julie Walters` character Molly Weasley for `Harry Potter and the Deathly Hallows: Part 2`, reported Contactmusic.
"You should warm up before sword fighting, that`s what Julie and I found out when we were duelling with each other. We were crippled after that scene! Duelling going backward on a table is tricky, without falling off. Which, of course, I did," said the Oscar nominated star of `The King`s Speech`.
The duel became a source of amusement for the film`s cast and crew because they watched the two actresses go from being friends to mortal enemies every time the cameras rolled.
"They could`ve sold tickets for filming that scene. They were chatting one minute and cutting each other to bits the next. It was brilliant," said Mark Williams, who plays Arthur Weasley in the film.
