Nick Cassavetes' “Yellow,” a featured title at the upcoming Toronto International Film Festival, has been picked up for international distribution by the Munich-based sales and production company Atlas International Film.

ICM is handling domestic sales on the drama, which makes its world premiere at the festival next month.

With a large ensemble cast, including Sienna Miller, below left, Ray Liotta, Lucy Punch, Melanie Griffith and Gena Rowlands, the story follows a young teacher with a drug problem.

Mary Holmes looks like she has the perfect life with four children and a great job. But the pills she swallows each day fuel a hallucinatory world, filled with colorful characters including Busby Berkeley dancers, Cirque de Soleil circus freaks, and human farm animals.

Founded in 1967, Atlas is now representing an increasing number of English-language titles, under the direction of co-presidents, Philip and Stefan Menz, the sons of the company’s founder, Dieter Menz.

Atlas is also handling international sales on the adaptation of “A Good Marriage,” a short story from Stephen King’s award-winning book “Full Dark, No Stars.” Joan Allen is in negotiations for the female lead, an individual familiar with the negotiations told TheWrap. Peter Askin is reportedly directing.

Other English-language titles on the Atlas slate include “Sweetwater,” starring January Jones and Ed Harris, and “Sofia” (“Assassins Bullet”) with Christian Slater. Glenn Ackermann is in charge of program sales.
