Lionheart is a 1968 children's adventure film directed by Michael Forlong and starring James Furlong, Louise Rush, Robert Dean and Pauline Yates. It was written by Forlong based on the 1965 novel Lionheart by Alexander Fullerton.
A young boy rescues and protects an escaped circus lion.
Sponsored by the Children's Film Foundation, the film was classified as "universal" suitable for audiences aged four years and over.
The Monthly Film Bulletin wrote: "A rather leisurely children's film whose main attraction is a huge lion, magnificent in appearance but disappointingly (if understandably) lethargic in performance. Guest appearances from Jimmy Edwards, Irene Handl and Joe Brown eke out a very flimsy narrative; and though the few snatches of suspense and bits of mild comedy may be acceptable makeweights for younger children, the pace is generally too slow to generate more than a modicum of excitement."
