La grande magia(1964)

Amongst the guests of the Metropole Hotel there is Calogero Di Spelta ridiculed for his unnecessary jealousy towards Marta, his beautiful wife. The illusionist Otto Marvuglia during his show pretends to make her disappear, and this allows her to meet her lover Mariano D'Albino. But Marta definitively escapes while the magician makes Calogero believe that his wife's in a box, and that she could reappear only if he blindly believed in her loyalty.
