Rip Van Winkle (1978)

Rip Van Winkle, a lazy American man, wanders off one day with his dog Wolf into the Kaatskill mountains where he runs into an odd group of men drinking and playing bowls. He drinks some of their mysterious brew and passes out. When he wakes up under a tree he is astonished to find that 20 years have passed and things are a lot different. This is a charming story about how America changed due to the revolutionary war, only in a different and more subtle way than ever told before.
