The chopped her locks into a pixie cut back in 2013 after having to wear her hair in a bowl cut-esque style for a movie role.

Maggie plays a woman called Nessa Stein, who witnessed the assassination of her father by the Palestinian Liberation Organisation when she was a young child. Now an adult, she's working within the Middle East peace process, but ends up in the midst of a mystery when a Palestinian man she awards a lucrative business contract to is found dead.
