Christian The Lion
In the 60’s, John Rendall and Ace Berg got themselves a baby lion. They named him Christian. For years they raised him as their pet, but when Christian got too big to care for, John and Ace worked with an environmentalist to reintroduce Christian back into the wild in Africa. After a year, John and Ace went back to Africa to find Christian, even though many people told them that the he would never recognize them.
