Jacob Elordi details 'obsession' with Margot Robbie after the pair filmed together for upcoming movie

Jacob Elordi has expressed his 'obsession' with Margot Robbie after the pair worked together on the upcoming movie, Wuthering Heights.

The Euphoria actor sat down with Robbie to promote the romance film, which is set to release in cinemas across the world next month.

Wuthering Heights is the latest creation from Saltburn creator Emerald Fennell, with it being loosely inspired by Emily Brontë's iconic 1847 novel of the same name.

Fennell has defended her choice of casting, after fans pointed out that 35-year-old Robbie is playing Catherine, a character originally written as a teenager, while Elordi's character of Heathcliff is described in the novel as 'dark skinned'.

She told the BBC that Robbie is 'not like anyone I've ever met - ever - and I think that's what I felt like with Cathy', and said of Elordi that he 'looked exactly like the illustration of Heathcliff on the first book that I read'.

Well, based on the chemistry Elordi and Robbie have described on set, it should be electric come February 11.

Sitting down with Fandango, Elordi discussed the dynamic he and Robbie shared on screen, with the latter suggesting the feeling was 'mutual'.

"We have a mutual obsession," Elordi told the entertainment platform.

"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 5 to 10 meters 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."

Elordi went on to say that they shared 'moments looking at each other in character' when they could feel the love for each other, which he hopes will come across on-screen and make it as authentic as possible.

"The moments when it was good and the love was alive were really sort of pleasurable moments to actually see, because in the book you don’t see them together," the 28-year-old added.

"But to actually confirm that love in our version of the narrative, and to see it lived through, was a pretty profound experience."

Robbie, meanwhile, went on to say that even when she isn't filming scenes with Elordi, her character is 'talking or thinking' about him.

She added: "They are focused on each other in every single thing they do, which is a really nice and straightforward thing to do."

Robbie went on to explain the character was much easier to play compared to a character who has 'vague ambitions'.

She also stated that if she was constantly thinking about Elordi's character 'then she was doing her job in every scene'.
