This is just Dissociative Identity Disorder Day! How so, you say? Well, tasty former “The OC” nerd Autumn Reeser, along with Trent Ford and Jamie Murray have joined the indie psychological dramedy POSSESSIONS. Under first-time writer/director Nathan Adolfson, Ford plays a suicidal man with cancer who seems to suffer from DID seeing as how he’s haunted by a Frenchman’s voice in his head who’s intent on taking him over. What’s more, “the man and the voice in his head form an odd quadrangle with Murray and Reeser,” whatever the hell that means. Presumably, that means tons of hilarity mixed with a little drama. Production is expected to begin this Friday in LA. Reeser can next be seen getting in on some vampire action in the sequel LOST BOYS: THE TRIBE.
