Dan Aykroyd’s Haunted House

One of the original Ghostbusters, Dan Ackroyd hasn't been able to rid his former home (which is now owned by Beverly D'Angelo) of the ghost of Mama Cass. The Mamas and the Papas' Cass Elliot, Ackroyd, and D'Angelo are only a few of this L.A. home's famous residents; others include A-list celebs such as Natalie Wood, Ring Star, Alfre Woodard, and Renee Zellweger.
