Aggar (2007)

Aditya is a successful businessman whose marriage to Neha, a psychologist, has begun to fray under suspicion. Into their lives comes Ronnie, a disturbed young man whom Neha treats and who becomes obsessed with her. As jealousy, manipulation and secrets pile up, it becomes hard to tell who is using whom, and the film turns into a psychological thriller with twists in its last act. Aggar was directed by Anant Mahadevan, who had made Aksar with Udita Goswami a year earlier, and it gave Shreyas Talpade, then known for gentle roles in Iqbal and Dor, a darker part as the obsessive patient. Mithoon's soundtrack was the most remembered part of the film.
