Who was the only person to have a spoken line in Mel Brooks' "Silent Movie"?

Silent Movie is an American satirical comedy film co-written and directed by and starring Mel Brooks, released by 20th Century Fox on June 17, 1976. The ensemble cast includes Dom DeLuise, Marty Feldman, Bernadette Peters, and Sid Caesar, with appearances by Anne Bancroft, Liza Minnelli, Burt Reynolds, James Caan, Marcel Marceau, and Paul Newman playing themselves. While indeed silent (except for one word, music, and numerous sound effects), the film is a parody of the silent film genre, particularly the slapstick comedies of Charlie Chaplin, Mack Sennett, and Buster Keaton. Among the film's most famous gags is the fact that the only audible word in the film is spoken by Marcel Marceau, a mime. Sound is a big factor in the film's humor, as when a scene that shows the New York City skyline begins with the song "San Francisco", only to have it come to a sudden stop as if the musicians realize they are playing the wrong music. They then go into "I'll Take Manhattan" instead. The trend of large corporations buying up film studios is parodied by the attempt of the Engulf and Devour Corporation to take control of a studio (a thinly veiled reference to Gulf+Western's takeover of Paramount Pictures).
