There's something indescribable about the stuff we watch as children, then watch again as adults. The CBS Children's Film Festival from 1967 showed two movies that made quite an impact on me at age 10.
I've alrady posted "Skinny and Fatty", the 1959 movie from Japan. If you like I can repost it along with the other film I've never forgotten:
"Hand in Hand" - 1960
This movie concerns the friendship between a Catholic boy and a Jewish girl. He thinks his friend drowned in the river when she fell off their raft so the movie is told in flashback style.
