"Buffy the Vampire Slayer" star Sarah Michelle Gellar will star in Ellen DeGeneres produced thriller series "Sometimes I Lie" for Fox. "Sometimes I Lie" will be based on the life of former BBC journalist Alice Feeney's novel of the same name. The potential series alternates between her paralyzed present, the week before her accident and a series of childhood diaries from 20 years ago.

The limited series revolves around Amber Reynolds (Gellar) who is in a coma and can't remember how she got there but knows it wasn't an accident. Terrified and trapped in her own body, she tries to piece together her memories of the past week. With a husband who no longer loves her, a sister hiding a dangerous secret and an ex-boyfriend who can't let go of her, Amber knows someone is lying and that her life is still in danger.

"Sometimes I Lie" will be written by Robin Swicord, who will serve as an executive producer along with Ellen DeGeneres. Ellen Degeneres and Jeff Kleeman will serve as producers on the project.
