Do not, we repeat, do not pinch Gemma Arteton’s bum otherwise she’ll punch you in the face. We don’t think being homeless is a factor, but the guy she smacked certainly was.

Sitting on Graham Norton’s sofa, she regaled the Irish comedian and audience members, recalling: “I was in one of those ATM rooms and there was a tramp. He kept looking at me and then he grabbed my bum really hard. I properly punched him in the face. I then realised I’d punched a tramp so I ran.” The erstwhile Bond girl added, “Thank God he didn’t punch me back. I actually felt quite bad about it.” So let that be a lesson to you; don’t be pinching Arteton’s bum (or anyone’s for that matter) or you’ll get an almighty face-smack! She may have been taking influence from her character of Gretel in Hansel and Gretel: Witch Hunters. "One of the reasons I wanted to do the film is because I've always wanted to punch people. It was fun," she explained.

Perhaps her upbringing, which lead her to being a proud feminist, was part of the reason behind her unflinching treatment of the bum-friendly tramp. “She is the most amazing woman,” said Arteton of her mother in an interview with the Telegraph. “She is responsible for my sister and me being the people we are: quite open, sensitive and compassionate. We had a very liberal upbringing, with lots of music, culture, theatre. But she wouldn’t let us go crazy and off the rails. She keeps us rooted in reality, with our feet on the ground.”
