Do Vinci Movie Madness is the 29th episode of the 2013 series of Calimero.
In this episode, Calimero and friends find an old film made by Do Vinci but it snaps while being played. Valeriano takes it to the movie theater to use a machine that will repair it, but he accidentally gets it switched with the movie to be shown at the theater later that day, which would mean Do Vinci's secrets would be revealed to the town. So Calimero and the others have to get it back and replace it with the real movie before it's too late.
