Hayley Atwell has revealed she got to grips with Chris Evans' pecs in Captain America.
The British actress, who plays a British military agent in the superhero film, couldn't resist feeling the actor's chest when the cameras were rolling - with the scenes making the final cut.
"When Chris Evans first took his shirt off on the set of Captain America, I just instinctively grabbed his man boob. They kept it in the film," she told US Esquire.
"So we did a couple of takes of me being really inappropriate with my hand on his pec for the duration of the scene."
Hayley, best known for appearing in period films like Brideshead Revisited, The Duchess and TV miniseries The Pillars Of The Earth, also admitted she was intimidated by Captain America co-star Tommy Lee Jones, who plays an American military officer.
"Tommy Lee Jones is really scary. Because he'll take his time answering a question. It feels like he's ignored you," she said.
"He does it long enough for you to feel completely humiliated. I said hello to him and then there was a long pause and then he said, 'Do you like opera?' He's got a very, very dry sense of humour."
