Pierce Brosnan's Ghostly Return to TV

Pierce Brosnan plays a writer grappling with grief in the Stephen King's Bag of Bones, airing Sunday and Monday on A&E, and the veteran star exclusively tells ET of the gripping ghost story, "This is a beast of a piece."

Marking the former Remington Steele star's long-awaited return to television, Pierce is also a producer on the four-hour miniseries and says with a grin, "You want the audience to just go, 'Wow, what's gonna happen next?'"

Based on King's bestselling supernatural thriller, Pierce plays Michael Noonan, a bestselling novelist who is unable to stop grieving after the sudden death of his wife (played by Annabeth Gish). Suffering from writer's block, he takes refuge at their lakeside retreat in western Maine, only to be plagued by ever-escalating nightmares, ghostly visitations from a blues singer (Anika Noni Rose) and past secrets coming to light.

"My life is backed into this chaotic, apocalyptic turmoil of the heart and the psyche," explains the former 007 of his character's incredible loss. "In going back to this lake house he begins to unravel the mystery of his own life."

Melissa George, William Schallert, Jason and Caitlin Carmichael also star.
