The Lamb is a 1915 American silent adventure comedy/Western film featuring Douglas Fairbanks in his first starring role.
 Directed by W. Christy Cabanne, the film is based on the popular 1913 Broadway play "The New Henrietta", in which Fairbanks co-starred with William H. Crane, Amelia Bingham and a very young Patricia Collinge.
 D. W. Griffith, writing under the pseudonym Granville Barker, along with director Christy Cabanne, essentially expanded the play beyond the plush nouveau riche apartment setting of the play, and provided a western element to the story.
 This would give Fairbanks a chance to show his physical prowess cinematically and loosen the play from what would be stage bound constraints.
 Griffith also altered characters; Fairbanks' character's name is changed to Gerald, with his parent being his mother (Kate Toncray), whereas in the play his character was named Nick with his parent being his father played by Crane.
