Wilson was no stranger to the Magic Castle's Houdini Room. He also created the "Aquarian Illusion," a cross between Houdini's Water Torture Cell and Metamorphosis. You can watch him perform it on the 1981 HBO special Mumbo Jumbo. It's Magic! on YouTube.
It was always a thrill to see Mark, his wife Nani, and son Greg at Magic Castle functions. I never got over the fact that I was in the same room with a legend.
R.I.P. Mark Wilson. One of the greats!
