One of my favorites. This is a strange movie, no doubt about it. The animation is colorful and psychedelic. Things that happen in this movie could only happen in an alternate dimension or a long dream.
The basic premise of the movie has peaceful, beautiful Pepperland under attack by curious blue creatures called Blue Meanies who hate beauty, music, and happiness. They "bonk" people with green apples and turn them to stone. Young Fred (actually a middle-aged guy) takes the fabled Yellow Submarine, a sort of ark that brought his ancestors to Pepperland, and travels through strange lands until he reaches London. There he meets Ringo, bored in a polluted gray city. Ringo convinces his three friends who live with him in a fabulous museum to help. They travel back, meeting strange creatures and picking up Jeremy (The Nowhere Man) along the way. When they reach Pepperland, they conquer the blue meanies with music, poetry, and love.
There are many Beatles songs, including the title song, "When I'm 64," "All You Need is Love," "Sergeant Pepper's Lonely Heart's Club Band," and more.
Young kids may be disturbed by some of the strange images.
