The work of Italian director Federico Fellini (1920–1993) has been consistently addressed by both Allen and his critics as one of the American's key European influences, one that became apparent in 1965's What's New Pussycat?, a dream scene containing "clearly a parody of Marcello Mastroianni's dream in Fellini's 8½ (1963)" (Yacowar 33) and continued surfacing throughout Allen's directorial activity in the 1970s, for example the "ironic illusion to Fellini's contribution to Boccaccio "70 (1962)" (Yacowar 147–148), carried out by the representation of a billboard with breasts in 1972's Everything You Always Wanted to Know About Sex.
