Oscar Isaac has admitted stripping off for Madonna on the set of her new film was "incredibly intimidating".
The Sucker Punch actor filmed a passionate love scene for the Queen of Pop's latest movie project W.E, playing a Russian security guard who embarks on an affair with New York socialite Wally Winthrop (Abbie Cornish).
Oscar said of his superstar director: "She was adamant that both men and women scream when I take my shirt off so I had to do a lot of training for that. I was passable by the end she said!"
He went on: "That was something actually. Having to do a love scene with Abbie (Cornish) and then having Madonna yelling direction about how to make love better was definitely a surreal moment."
The film, which Madonna also co-wrote, focuses on the affair between King Edward VIII (James D'Arcy) and American divorcee Wallis Simpson (Andrea Riseborough), plus the contemporary romance between Oscar and Abbie's characters.
Oscar revealed gym fan Madonna was keen to ensure his physique looked the part.
"(It was) incredibly intimidating, she really inspected to make sure every muscle was in its place. But it was an amazing experience doing that film and I'm really excited to see it."
