Helena Bonham Carter has a love/hate relationship with Hermione Granger. She enjoys toturing Harry Potter’s good friend, but also wants to be her. Or maybe that’s Carter’s character, Bellatrix Lestrange. Either way…

The actress recently spoke to MTV and shared some tidbits about the upcoming Harry Potter and the Deathly Hallows movies, which will see the final book in the Potter series split into two, and be released in 3D.

The evil Deatheater Bellatrix has already murdered Harry’s godfather Sirius Black (played by Gary Oldman), but her dreadful deeds don’t end there. And Carter enjoys the evil!

“I get to torture Hermione,” Carter reportedly told MTV when asked about her favourite scene, before going on to elaborate on her Hermione fixation. “The best bit about being Bellatrix in this one is also because I got to pretend to be Hermione,” she said, speaking of a scene in which Hermione assume Bellatrix’s identity in order to gain access to Gringotts Wizarding Bank. “Because Hermione takes polyjuice potion and gets to look like Bellatrix.”

It seems the studio decided it was easier to dress Helena as Hermione than to turn Emma Watson into Bellatrix. “Rather than put Emma Watson in a helluva load of make-up they just said, ‘Now you go act like Hermione,’” Bonham Carter explained. “That was fun, because I always wanted to be Hermione.”

But you won’t see it until the second movie comes out, says Carter – “all of my stuff is in the second one. So you won’t see me until 2011.”

Part 1 of Deathly Hallows hits theatres in November, 2010 and part 2 in July, 2011.
