Kristen Stewart will film a small role in new indie drama 'Anaesthesia'.

The 'Twilight' actress has joined the cast of Tim Blake Nelson's new ensemble drama, which follows a group of university students whose philosophy professor has a profound effect on their lives.

Deadline reports Stewart will shoot her scenes over the course of a ''few days''.

The actress' latest role joins a busy schedule of movies including politically-charged thriller 'Camp X-Ray', directed by Peter Sattler, and Oliver Assayas' new drama 'Sils Maria'.

In 'Camp X-Ray', Stewart plays a young woman who joins the army in a bid to escape her small-town life, only to find herself sent to work at Guantanamo Bay detention camp. Suffering from abuse from the men in her charge, she forms an unlikely bond with a man who has been incarcerated for eight years.

Stewart will then join an A-list cast including Juliette Binoche and Chloe Grace Moretz in 'Sils Maria'.

French filmmaker Assayas wrote the film about an actress suffering from a midlife crisis specifically for Binoche, who he worked with on 'Summer Hours'. Binoche's character becomes obsessed with a young actress (Moretz) who is playing the part which originally made her famous, while Stewart has been cast as Binoche's assistant.
