“Sex scenes can be quite awkward,” Michael Fassbender has said. From Keira Knightley: “I did a couple shots of vodka beforehand.” “I mean, regardless there’s like 150 crew men watching and you see each other’s bits and pieces. The whole thing is just wrong,” Mila Kunis has added. Poor Henry Cavill, who did “get a bit hard” after an actress with “spectacular breasts” simulated a sex scene with him in The Tudors has said: “It’s actually acutely uncomfortable being naked in a roomful of people. The very last thing it is sexy.”
