Helena Bonham Carter is very into exploring the role of the bad guy (or girl) these days.
After coming off her noteworthy turn as Mrs. Lovett opposite Johnny Depp in Sweeney Todd and a recurring role as Bellatrix Lestrange in the Harry Potter franchise, Bonham Carter is now in talks to take on the part of the primary villain in Terminator Salvation. It is unknown whether bad Bonham Carter is to be cyborg or human.
The British actress, who got her start as a Merchant Ivory typecast, first went bad in a major box office way in Fight Club and evidently has been exploring her love affair with the dark side ever since.
