'Suicide Squad': Comic villains on film - CNET

While the team called Suicide Squad was introduced in the comic The Brave and the Bold #25 way back in 1959, Harley Qui only became a member in 2011. In fact, she wasn't even a comic character originally, first appearing the 1990s "Batman: The Animated Series".

In the movie Harley Qui -- real name Harleen Quinzel, a psychologist -- is played by Australian actress Margot Robbie. She swings a baseball bat instead of a comically oversized mallet, but has the same quirky and uninhibited attitude as her comic book character, not to mention the same troubled relationship with the murderous Joker.
