The film was a great success, De Sica and Lia Franca became stars and the song Parlami d'amore Mariù was a hit. Rarelly in Italian film history, it was filmed on real Milan locations, nowadays it is a sort of documentary how was Milan in the 30s. The film was remade in 1953 by Glauco Pellegrini.
The story is said to follow a pair of loner college undergrads, Jack and Montgomery, who order a take-out pie, but accidentally take a homemade drug that turns a two-floor journey downstairs into a “mind-bendingly transformative quest.”
