Remember that upcoming thriller about the woman who thinks it's a good idea to starve and isolate herself for a month to rid herself of her mental issues? Well, that's Waking Madison, and The Hollywood Reporter have posted the next round of cast members. Disturbia's Sarah Roemer is already set to star as the woman who "locks herself in her apartment for 30 days with no food, telephone, or outside stimuli," and Elisabeth Shue was cast as her doctor. Now we've got Frances Conroy, Will Patton, and word on Taryn Manning's character.

Conroy, who made a neurotic name for herself as Ruth Fisher on Six Feet Under, has been pretty well-cast as Dolly, "Madison's mother and a religious zealot who has her own mental-health issues," while Patton, who was most recently in A Mighty Heart, will play her dad, who is "loving but emotionally absent." Yet somehow, even though Madison has got a whole life of dysfunction, she thinks starving herself for a month will help heal her. Anyhow, Manning, whose casting has been listed on the film's website for a while, is playing Margaret -- "a fellow patient with sociopathic tendencies who resides at the psychiatric hospital with Madison." I'm not sure how Roemer's character can live in a hospital and an apartment, but we'll see soon enough. (Fie vague, confusing plot descriptions!) Production begins in New Orleans today.
