There’s plenty of action in Charlize Theron’s movie Atomic Blonde – but it’s the lesbian s=x scenes that have everyone talking.

In one scene, Theron’s secret agent character beats up plenty of men before seducing a French operative, played by Sofia Boutella.

Theron, 41, says locking lips and romping around with her s=xy co-star was “a great day at work”.

“Seducing her, it’s very easy, she’s gorgeous!” she told Entertainment Tonight Canada.

“She (Sofia) was just great. She was the only actress that we looked at.

“She came over, she hung out with me and (director) Dave (Leitch) and there was something about her that was so genuinely innocent and yet incredibly strong, that she was really perfect for the film.

“I can’t imagine anyone else doing it. She’s a dancer, I’m a dancer. So, we’re a little bit like – you know dancers are like … being naked is nothing.

“We just wanted it to be real and cool.”
