7 Faces of Dr. Lao - Production

Production

According to notes on the Leigh Harline soundtrack CD released by Film Score Monthly, Pal's first choice for the role was Peter Sellers who was strongly interested in the role. MGM decided that they wished an American in the lead role.

William Tuttle received an honorary Oscar for his makeup work on this film. It was the first of only two honorary Oscars awarded for makeup; the other went to John Chambers in 1968 for Planet of the Apes. As part of Tuttle's work, Randall had his head shaved, not only to play the bald Dr. Lao, but also to make it convenient for the "appliances" he had to wear. Randall later said, "It gave me an unborn look." The studio publicity department arrived at the barber too late to photograph the process, so they had a make-up artist glue hair back on Randall's head and the barber once again removed it, this time for the cameras. Randall makes a cameo appearance in the film, sans makeup, during the parade of cast members before the Woldercan sequence, sitting in the audience. Since his head was already shaved, makeup artist Tuttle applied a hairpiece to him. Randall later said in an interview, "Gene Kelly's old toupee came in handy."

Jim Danforth's model animation of the Loch Ness Monster, the Giant Serpent, Medusa's snake hair were nominated for an Academy Award.

The "Woldercan spectacular" that Dr. Lao presents as the grand finale of his circus contains much footage from an earlier George Pal production, 1961's Atlantis, the Lost Continent as well as some footage of flowing lava from The Time Machine and stock footage of destruction from MGM's 1951 production of Quo Vadis.

The crystal ball and large hourglass used by the Wicked Witch of the West in 1939's The Wizard of Oz can both be spotted in the film. Also, in the scene where Mike visits Lao at night, a two-headed tortoise can be seen; this made a few later appearances in the television series The Addams Family.
