Any man who plays Tarzan needs to be tough, but it wasn't the animals or tribal warriors that were Alexander Skarsgard's biggest threat.

The Swedish actor had to face a beating from Australian actress Margot Robbie who plays Jane to his Tarzan in the upcoming movie incarnation of the familiar tale.

However, it was all in the name of passion as Skarsgard says the injuries came from their sex scenes. Robbie also revealed to the media that she actually punched her co-star during these passionate moments, but Skarsgard says there was method to this madness.

"There is a sex scene in the movie when they return to the Congo village where Jane grew up and it's the first sex scene in the movie. Soon after that they are torn apart and the drive is for them to get back together, so it's important to make it a passionate moment," Skarsgard said.
