Cara Delevingne, the British actress, who is playing a crucial character in the movie 'Suicide Squad', says she almost felt like losing her "f***ing mind" during her shots for the director David Ayer's anti-hero-led movie.
The supermodel-turned-actor also revealed that she even sometimes fantasised about killing people in what she terms as "demonic" moments while filming the movie.
"I tried to imagine the darkest s**t for a long time, like seeing people crumble and their skin melt in front of me or making people implode and trying to use my imagination in dark ways," Delevingne said.
"I remember seeing a guy behind a bar cutting up a cucumber then seeing him cut all the way up his hand and I thought, 'I'm losing my f***ing mind'," she added.
"Is this going to stick? Am I going to have to be sent in and locked away? I don't like being by myself anyway, but it was more scary when I was acting out the role. I didn't like going home and being alone with these thoughts," she added.
"When I was in the outfit, I was far more demonic than I'm shown on-screen, my character definitely felt evil and living in that was very emotional. I studied addiction, desperation, that void. It was draining, desperate, exhilarating and maddening," said the actress.
