It's very impressive movie.
Although they could not meet each other for a long time, Christian had remembered them, John and Anthony. This touching movie is a true story.
I love a pet. And I have a dog.
If I could tame a wild animal, I will choose a lion.

Love knows no limits and true friendship last a lifetime.
