Leo the Lion seems to have been released at a time when lions were "hot."
The release date of this film coincides with the 1994 release of a redone "Kimba the White Lion" series on television, and of course The Lion King in theaters.
In fact, The 1994 release of Kimba shares voice talent with Leo the Lion.
I suggest that you simply find DVDs of Kimba from the 60's or view the 1997 theatrical release of Osamu Tezuka's Jungle Emperor Leo, which is also out on DVD and can be found on IMDb.
A word of warning though. Jungle Emperor Leo, although animated, is probably not for younger children.
