A forthcoming Woody Allen film will feature a character being accused of sleeping with a 15-year-old girl, with a plot twist later revealing that she is in fact 21.

According to Page Six, the untitled film, which just completed production, stars Jude Law as a middle-aged married man who embarks on affairs with several much younger women.

One scene depicts his wife, played by Rebecca Hall, accusing him of having sex with a 15-year-old "concubine" played by Elle Fanning. In a sex scene, Fanning's character protests that she is in fact 21. She then asks Law's character: "Were all these women for pleasure, or were you researching a project?"

Little is known about the premise of the forthcoming film, which also stars Selena Gomez, Suki Waterhouse and Call Me By Your Name actor Timothée Chalamet, but the described scene seems to mirror a similar subplot in Allen's 1979 romantic comedy Manhattan, in which he played a 42-year-old sitcom writer in a relationship with a 17-year-old girl.

81-year-old Allen, who is married to the adopted daughter of his former partner Mia Farrow, was previously accused of sexually abusing his daughter Dylan Farrow when she was seven years old, an allegation supported by Allen's son Ronan – the author of an expose on Harvey Weinstein published two weeks ago in the New Yorker.
