Ivan Tors first discovered Clarence at Africa, USA, an affection training compound located in Soledad Canyon near Los Angeles. Born cross-eyed, Clarence's strange physical condition inspired Ivan Tors to create the MGM feature film "Clarence the Cross-Eyed Lion" and the spin-off series Daktari. When the audience saw what Clarence saw, it was in double vision. Reportedly, Clarence was very good with children. Another not so friendly lion named Leo doubled for Clarence in some scenes. He was used only for the snarling scenes and general scenes which didn't involve close proximity with humans. Leo had come to Africa, USA from a family in Utah. His ferocity was due in part to the mistreatment he received from former owners who reportedly beat him with a stick
