She'll star opposite Tye Sheridan in the thriller.

Ahead of the Sundance premiere of her film The Diary of a Teenage Girl, Bel Powley has signed on to indie Detour.

The psychological thriller will star Tye Sheridan as Harper, a grieving law student who, in an act of desperation, hatches a plot to murder his corrupt and abusive stepfather.

Powley will play Cherry, a stripper/prostitute who lends Harper a helping hand. The movie will begin principal photography in South Africa next month.

British filmmaker Christopher Smith (Get Santa) wrote and will direct the project. Jason Newmark and Julie Baines are producing.

Powley, whose theater credits include the West End plays Jumpy and Raving, has wrapped work on a trio of interesting films, with the first, The Diary of a Teenage Girl, premiering at Sundance.

She'll also star in Girls' Night Out as Princess Margaret, who sneaks out of Buckingham Palace to celebrate VE Day on May 8, 1945. The film, directed by Julian Jarrold, stars Sarah Gadon and Jack Reynor. The British actress also recently wrapped production on Drake Doremus upcoming sci-fi romantic drama Equals with Nicholas Hoult, Kristen Stewart and Guy Pearce. She's repped by UTA, Schachter/Brown and BWH in the U.K.
