Natalia Dyer and Danny Ramirez have been cast alongside Legion's Rachel Keller in an upcoming drama titled Chestnut.
The Stranger Things and Falcon and The Winter Soldier stars will appear in the upcoming queer love triangle drama.
It will also mark the feature length directorial debut for Jac Cron — whose short film House Sit won multiple awards in 2020.
Chestnut, which is set to launch at festivals early next year, will see Dyer as a graduate who finds herself unwittingly entangled in a relationship with a man (Ramirez) and a woman (Keller) during their summer holidays.

The queer drama, which wrapped production this month, was shot on location and takes its name from Philadelphia's cornerstone of queer culture.
The cast also includes Titans' Chella Man and Judas and the Black Messiah actor Caleb Eberhardt.
As well as Stranger Things, Dyer has also appeared in Yes, God, Yes, which, according to the List, made the young star realise the importance of dealing with teenage sexuality.
She previously explained: "Teenage sexuality is funny and beautiful and awkward and embarrassing."

She continued: "I grew up watching interpretations of females, but it was never like, 'That's me,' it was always like, 'Oh, that's how I'm supposed to look, talk and feel in order to get the guy, or whatever.'
"So it's really important to have films like Yes, God Yes, especially when it comes to displaying women and sex, what they want and how they behave."
Meanwhile, for Ramirez, in addition to his Marvel fame, he is also known for his character Mario Martinez in On My Block and will next be seen in the upcoming Tom Cruise starrer Top Gun: Maverick.
Stranger Things seasons 1-3 are now streaming on Netflix, and season 4 is due to premiere in 2022.
