Sisters Dakota and Elle Fanning have appeared in several films together, but it was only when they featured in the same scene in their upcoming movie that they had their first on-set "fight."
The talented duo is starring in The Nightingale, based on Kristin Hannah's novel of the same name, but things became tense between them during one uncomfortable scene.
"Right towards the end, there was a scene we were doing together, and it was this really hot room, and we were on this couch, and I was like, 'Move your leg!'" Dakota, 32, recalled on Tuesday's episode of The Tonight Show Starring Jimmy Fallon.
"She was like, 'My leg has been here all day!' And I was like, 'No, it hasn't. Get off of me! I'm too hot. You're sweating on me'… I was like, 'Stop talking!'"
Dakota continued: "It was the only quote-unquote 'fight' — but the crew was dying because we had kept it so together the whole time. It was totally a sister tiff."
While they have both starred in films including 2001's I Am Sam and 2005's My Neighbor Totoro, where Elle, 28, played younger versions of Dakota's characters, Dakota explained that The Nightingale is the first time they have acted alongside each other.

"It's the person that knows you the best in the world that you're acting with," she added. "We're super close, and we were a little silently panicked."

"I had to treat her like I would treat any other actor," Dakota explained, although she confessed that she struggled to follow Elle's rule.
Dakota and Elle's real names

The sisters were both born with different monikers from the ones they use. Dakota was born Hannah Dakota Fanning, while Elle's full name is Mary Elle Fanning.
The sisters' mom, Hannah Joy Arrington, also goes by her middle name, a tradition she passed down when her daughters were born.

The star added during her chat with Glamour that this at times caused confusion during her childhood. "It was awkward in school when they were calling roll call because they'd go, 'Mary? Mary?' Kids would be like, 'There’s no Mary here.' I'd awkwardly raise my hand, like, 'Uh, it's me.'"
