The House That Shadows Built (1931) is a short feature, roughly 48 minutes long, from Paramount Pictures made to celebrate the 20th anniversary of the studio's founding in 1912. It was a promotional film for exhibitors and never had a regular theatrical release and includes a brief history of Paramount, interviews with various actors, and clips from upcoming projects (some of which never came to fruition). The title comes from a biography of Paramount founder Adolph Zukor, The House That Shadows Built (1928), by William Henry Irwin.
