Jacob Elordi and Margot Robbie have 'mutual obsession' with each other

Jacob Elordi has an "obsession" with his Wuthering Heights co-star Margot Robbie.

The 28-year-old star plays Heathcliff in Emerald Fennell's upcoming adaptation of Emily Bronte's novel and revealed that he was transfixed by his fellow Australian during the making of the movie.

Jacob told Fandango: "We have a mutual obsession.

"I think the thing is, regardless of plot or screenplay, if you have the opportunity to share a film set with Margot Robbie, you're going to make sure you're within five to 10 metres at all times.

"Watching how she drinks tea, how she eats her food, how she does it. When is it going to slip? When is the thing going to come undone? And, it never comes undone."

Jacob and Margot play star-crossed lovers Heathcliff and Catherine in the film and the Euphoria actor felt that the pair were totally immersed in the story.

He recalled: "There'd be a moment where we'd be running hand-in-hand through the moors - maybe not even in the scene, just setting it up - where I'd look across at her and she'd be looking at me... and in that moment, we really were a part of their love, for real."
