Tell us about your character.

Michelle is the CEO of a pharmaceutical company and her natural way is being in charge, even amid an insane situation after she's kidnapped. It's very complex trying to get out of what she's in, so she finds herself lying about things, then telling the truth, but nobody really realises what that is exactly. Walking that line between what is true, what is false, what is her real character and what's a performance - it's a complex, delicate balance.

You had to shave your head for the role. Did you find that hard?
