Joining movie stars of the past and present, C-3PO, one of the famous robots from the 20th Century-Fox film “Star Wars”, places his foot prints in the cement in front of Mann's Chinese Theater in Los Angeles, Calif., August 3, 1977. Assisted by studio personnel, C-3PO signs his name and thereby joins such stars as Greta Garbo, Clark Gable and Barbra Streisand.
