The British model-turned-actress is starring in DC Comics' upcoming feature Suicide Squad alongside the likes of Will Smith, Ben Affleck, Margot Robbie and Jared Leto. Though the plot of the new film is shrouded in secrecy, Cara is known to be playing Dr. June Moone, who is a shy scientist-type during the day but by night morphs into the wildly seductive Enchantress. The double identity concept is a subject which interests Cara, who admits she was fascinated by comic book character Peter Parker and his alter-ego Spider-Man when she was growing up.

"It was the sense of dressing up and feeling really tough," she told W Magazine. "I only dreamed of being male superheroes. Spider-Man, especially, had a cool costume and cool toys. There were not many strong superhero-type women, apart from Wonder Woman - but I didn’t want to be a 5-year-old running around in, like, a bikini."

The 23-year-old adds that when she first auditioned for the part, director David Ayer didn't tell her anything about the premise of the movie. Instead, he showed her pictures of "powerful, but very evil" women and at a later date asked her to read a scene from play Who’s Afraid of Virginia Woolf?

"I love that play and had acted in it at school when I was 17, so I was excited. Somehow, when we were doing the scene, I became livid. I hadn’t felt rage like that in years," she shared of the challenging audition process, adding, "And then I got the part!"

While the Paper Towns star still does some modelling, and appears on the June/July cover of W magazine wearing a fluffy red Saint Laurent coat and matching tights, she is focused on developing her acting career and is seeking more demanding roles. For the past several months she has been filming Valerian and the City of a Thousand Planets, based on a popular French comic book from the 1960s and directed by Luc Besson. Cara portrays a character named Laureline, a space agent who solves crimes in intergalactic worlds, but admits that everything else about the plot is a secret.

"More is known about my life than the lives of the characters I play," she smiled. "My plan is to reverse that."

Suicide Squad is set to hit U.K. and U.S. theatres on 5 August (16).
