Now reader "JC" has altered me to another Houdini-Buster connection. Keaton's classic 1922 short COPS starts off with a quote from Houdini: "Love laughs at locksmiths."
In 1997 COPS was selected by the Library of Congress for preservation in their National Film Registry. So this cinematic nod to Houdini from the great Buster Keaton will now live forever.
You can watch COPS in its entirety on YouTube (Houdini quote is at 0:21).
Thank you JC.
