Three generations of Macks have led Filmack since 1919, starting with B&W silent nitrate film and now producing estar base film trailers with digital picture and sound technology. Irving Mack started Filmack Trailer Company in a small store front building just a few blocks away from the company's current production facility. Through the years many people started their film careers at FIlmack, including Walt Disney, who worked at Filmack as an animation artist in the 1920s. Today, Filmack Studios produces rolling stock film trailers for theatre circuits, independents, and on-screen advertising organizations worldwide that inform, promote, and advertise.
