When I was fortunate to be aboard the Queen Mary 2 for a month in her maiden season, Richard Johnson who played the psychiatrist "ghost hunter" in The Haunting gave a lecture on his career, theater, film and The Haunting. He ended an urban legend once and for all. The bending doors pushed by the spooks were not rubber. They were wood. Stage hands pushed against them. It was difficult but they did it.
Of course, after his lecture, we all watched The Haunting on the QM2's massive movie screen. And there were copies of the DVD of the movie available suitable for signing.
