Claustrophobic Crossing Jordan star Jill Hennessy was left terrified when she was briefly buried alive in a coffin during a night shoot for the show. The actress had nightmares about the scene, in which she lies in wait for a killer, before the coffin shots were filmed. The actor playing the killer accidentally slammed the lid to the coffin shut at the end of the scene, and the crew were so keen to move on to the next shot, they left the screaming Hennessy inside the box, contemplating a slow death.
