Zampi began his career as an actor in Italy at the age of 17. By 1930, he was working for Warner Bros. as a film editor in London. In 1937, he and compatriot Filippo Del Giudice founded Two Cities Films.^[4] While the company was noted for such serious films as In Which We Serve, Henry V, and Hamlet, Zampi is most remembered for comedies. He made his mark with such films as Laughter in Paradise (1951), The Naked Truth (1957), and Too Many Crooks (1959), often in the dual role of director and producer.
