PREVIEW: Actor John Cusack tells Soledad what it's like to be 'immersed' in a dark role, previews his upcoming role in "The Raven"

In this sneak peek, actor John Cusack talks with Soledad O'Brien for "Starting Point" about his upcoming role in the adaptation of Edgar Allan Poe's "The Raven," and explains why he was lucky to make it big after being a child actor in Hollywood.

In this preview clip, Cusack talks about the process of working in "The Raven" and explains sometimes it's hard to disconnect oneself from a character.

"With Poe, you immerse yourself in his stories and his vibe," Cusack says. "He had such a tragic life. He lost his mother to tuberculosis, lost his step mother, lost his wife. He was a haunted man. I think you have ot immerse yourself in that."

Cusack says it was also hard to return to everyday life after living in such darkness. "I felt a bit like a vampire when I was done," he says.
