The Technical Writer (2003)

Directed and co-written by Scott Saunders, The Technical Writer stars Tatum O'Neal as Slim, one of the tenants residing in a glamorous Manhattan apartment complex. Along with Joe (William Forsythe), her husband, Slim is determined to introduce the reclusive Jessop (Michael Harris) into her social circuit, which often involves swinging sex parties. Though Jessop isn't tempted, Slim, after having made a bet with her husband, continues to interrupt his isolated existence, and eventually succeeds in seducing the middle-aged loner out of his agoraphobia and into her bed. Once Jessop is hooked, however, Slim distances herself from him. The Technical Writer also features Pamela Gordon and Oksana Lada.
