Richard Shepard’s upcoming thriller “The Perfection” has added Allison Williams (Get Out, Girls) to the cast. The popular actor will take the lead in the film, which tells the story of two cello prodigies and a sinister obsession. Production on the thriller is currently scheduled to begin in early 2018 in Shanghai and Vancouver.

The film is a reunion for Williams and Shepard who previously collaborated on Golden Globe winning series Girls, including Williams’ standout episode, “The Panic in Central Park.”

The film’s script was written by Richard Shepard, Eric Charmelo and Nicole Snyder. The Perfection will be produced by Miramax CEO Bill Block, Richard Shepard and Stacey Reiss (The Eagle Huntress). Christian Mercuri’s Capstone Group is handling international sales for the film and will introduce the film to buyers at the upcoming AFM.

“It’s truly exciting to be reunited with Allison,” said Shepard. “Our time together during the six seasons of Girls was amazing. I loved watching her grow as an actress, and a person and I was thinking of her the entire time we were writing this movie. I can’t wait to bring a different side of Allison to the screen.”

Added Williams, “Ever since Get Out, I’ve been looking for a feature that had a similar magical alchemy to it – a writer/director I love, a subject matter that feels urgent and relevant, a character who fascinates me, and a script that feels almost too ambitious to pull off. The Perfection is all of those things, and I cannot wait to bring it to life so everyone can see why this project made me feel both eager and trepidatious (quickly becoming my favorite combination of sensations). Without spoiling it, I’ll just say this: we’ve all been talking about this movie — without realizing that we’ve been doing so. And I feel very fortunate and grateful to be able to take part in its realization.”

Williams is represented by CAA, Untitled, and Frankfurt Kurnit Klein & Selz PC. She will be seen next in Showtime limited series Patrick Melrose, opposite Benedict Cumberbatch.
