Spiral (2008)

Synopsis
Hatchet director Adam Green teams with that film's star Joel David Moore to craft this simmering psychological thriller about a reclusive telemarketer and artist who finds the many layers of his complex psyche gradually peeled away by a vivacious co-worker. Asthmatic cubicle dweller Mason (Moore) doesn't have many friends, and the closest thing he has to an actual relationship is his awkward interaction with his swaggering boss. All of that begins to change, however, when soul-searching newcomer Amber (Amber Tamblyn) lands a job at the office where Mason works. Amber is friendly but lonely, and on her quest to find herself she begins opens up to Mason and the two become fast friends. When Amber discovers that Mason is a gifted painter, she agrees to pose for a series of portraits. Recognizing the similarity between the portraits of herself and the portraits of a blonde waitress that Mason recently removed from his studio walls, Amber becomes curious about Mason's past and begins to look deeper into his personality. But Mason has his fair share of dark secrets, and as Amber begins to probe deeper, the familiar cycle of torment and destruction that Mason has kept from her begins spinning once again and soon threatens to consume them both. ~ Jason Buchanan, All Movie Guide
