Born Free (1966), the story of the lioness Elsa, based on the work by
Joy Adamson. He also directed episodes of
The Saint (1962),

Worzel Gummidge Down Under (1987). He was also attached in the 1970s to a proposed
Doctor Who (1963) movie written by
Tom Baker and
Ian Marter called "Doctor Who Meets Scratchman", which was ultimately scuppered by copyright issues and never made.
