According to a modern source, footage from this film was used in the 1950 film Two Lost Worlds. The picture was remade in 1967 as One Million Years B. C.. Twentieth Century-Fox released the remake, which was directed by Don Chaffey and starred Rachel Welch (see AFI Catalog of Feature Films, 1961-70).
