Lili Reinhart (Forbidden Fruits) has joined previously announced Melissa Leo (Passenger) in The Mannequin.

Plot details are under wraps for the serial killer thriller from Sean Byrne (Dangerous Animals).

The Mannequin is described as a “twisted, intense, and propulsive serial killer procedural.”

Byrne stated, “Lili has such a grounded, authentic screen presence that’s a captivating mixture of vulnerability, independence, intelligence, and courage. I honestly can’t think of a more committed and immersive screen pairing than Lili and the equally fearless Melissa Leo to take on a serial killer like no other.”

Producers on The Mannequin include William Woods, Maddy Falle for Page 12 Pictures Inc., and Kristian Moliere for Triptych Pictures.

Executive producers are Steven Schneider, Phil Hunt, Compton Ross, Charlie Kemball, and Jed Benedict for Sixth Dimension, Lili Reinhart and Catherine Hagedorn of Small Victory Productions, and Melissa Leo. 

The film comes from Studiocanal’s genre label Sixth Dimension, with production slated to begin this summer.
