In honor of his passing, Turner Classic Movies plans a Tony Randall film festival on Monday. Starting at 6 am, TCM will air seven of Randall's classic movies, including The Seven Faces of Dr. Lao, The Alphabet Murders and Pillow Talk. Meanwhile, David Letterman is mourning the loss of the 84-year-old Randall, who was a frequent Late Show guest. "He appeared on our show over 100 times," Letterman says. "Whenever we needed a big laugh, we would bring in Tony. He always made us better for having worked with him. We will miss him very much." Last night, Late Night with Conan O'Brien also paid tribute to Randall — the Max Weinberg Seven closed the show by playing the Odd Couple theme.
