Funniest Show on Earth

Funniest Show on Earth () is a 1953 Italian comedy film directed by Mario Mattoli and starring May Britt. It is the first Italian film in 3D.
It was filmed with a three-dimensional shooting system patented by Carlo Ponti and Dino De Laurentiis and called "PoDelVision" (from the initials of their surnames), which prescribed the simultaneous use of more cameras and then the printing of two identical copies of films: one for the left eye and one for the right eye.
The film is an explicit parody of Cecil B. DeMille's "The Greatest Show on Earth".
Plot.
In the circus a clown named Tottons Togni (Totò), forced to never remove his make-up to avoid revealing his real identity, is constantly haunted by the jealousy of three women (a lion tamer, a fantasist, a trapeze artist) and also by the investigations of a police officer.
