The Missing Link is a 1927 American synchronized sound comedy film directed by Charles Reisner and starring Syd Chaplin, Ruth Hiatt and Tom McGuire. While the film has no audible dialog, it was released with a synchronized musical score with sound effects using the Vitaphone sound-on-disc process. The title of the film is a reference to the so-called "missing link" that connects man and the ape. ()
