This movie inspired the writers of "Big" (with Tom Hanks). A kid goes to bed and wakes up an adult. Easy to watch and a good laugh. Renato Pozzetto way of looking ( or better glaring) at the camera, clumsy moves, and "faccione" (big face), create some good laughing moments. I saw this movie years ago, and i still remember laughing my head off in the cinema. Speaking Italian helps a lot when watching it. If you can find it (still) spend an hour, relaxing, but don't think about the big American production one (which came out a the following year).
