The Legend Of Tarzan
Margot Robbie has confessed to passing up work-out sessions in favour of trying out all of the pubs London has to offer while filming The Legend Of Tarzan Warner Bros. Pictures

Margot Robbie has revealed that she refused to slim down to portray love interest, Jane Clayton, in adventure film The Legend Of Tarzan. Her methods of persuasion? Arguing that it would spoil the authenticity of the picture if her character was super-toned.

Speaking in an interview with TV Week, the Australian actress explained: "It's the 19th century (in the film) – if she's got a bit of weight on her, it's probably a good thing. I'm not going to look thin just for the sake of it."

While that sounds like a very justifiable reason given the time period that the film is set, the 26-year-old went on to confess that she might have opted out of a tough exercise regime for selfish reasons too. "It was my first time living in London properly and I wanted to try every pub," she told the publication.

Robbie's co-star Alexander Skarsgard, who plays the titular vine-swinger, couldn't quite get out of his work-out schedule quite so easily however. The former True Blood star previously told ABC News that he would have to get up at 4.30am most mornings to train and that he would go for long periods of time without seeing his family and friends during the four months of shooting just to fit everything in.

Alexander Skarsgard wasn't quite so lucky however, having to exercise frequently and diet during the film's shoot Warner Bros. Pictures

It also recently emerged that throughout filming, he was mostly living off a diet of chicken cutlets and was consuming around 7000 calories a day to achieve his desired muscle mass.

"The diet - horrible!" he recently recollected to Us Weekly. "I've got to give credit to Guy, our chef. He had his hands tied – like, no sugar, no dairy. It was very strict. When we wrapped, I got in my car and went straight to my dad's. He loves to cook, so I spent four days on his couch being fed. It was the most incredible week: bone marrow, fried mozzarella, pasta, red wine. I was like, 'Ahhh'."

The Legend Of Tarzan can currently be seen in US cinemas and comes out in the UK on Wednesday (6 July).
