Irving Allen started his film career in 1929 as an editor. He turned to directing in the 1940s, and two shorts he directed, Forty Boys and a Song (1941) and Climbing the Matterhorn (1947), won Academy Awards. His feature film output, however, was not particularly successful, and in the 1950s he and producer Albert R. Broccoli formed Warwick Films in Great Britain to produce films there.
