Legendary movie critic Roger Ebert will wear a prosthetic chin on his new show, he revealed in his blog Wednesday (Jan. 19). “That’s not to fool anyone, because my appearance is widely known,” Ebert wrote, referencing his facial disfigurement from several surgeries following thyroid cancer. “It will be used in a medium shot of me working in my office, and will be a pleasant reminder of the person I was for 64 years.” The fitting and creation of the new chin took two years. “Two original models were too stiff, so that my head held upright reminded me of Erich von Stroheim in ‘Grand Illusion,’ ” he quipped. His Roger Ebert Presents At the Movies is set to debut Friday on nearly 200 stations nationwide.
