First, Billy Wilder's touching and funny romantic farce "Avanti!" focuses on a stodgy corporate executive (Jack Lemmon) who's in Italy to claim the body of his father, who has been killed in an accident. There he meets the daughter (Juliet Mills) of dad's mistress, and the two begin their own affair on their parents' favorite little island. Clive Revill, Edward Andrews co-star. Next, the Wilder/I.A.L. Diamond farce "Irma La Douce" stars Lemmon as a bumbling Paris gendarme who is fired for raiding the red light district (where his chief is a customer) and becomes an equally bumbling pimp for streetwalker Shirley MacLaine. Co-stars Lou Jacobi; Oscar-winning music by Andre Previn. 4 3/4 hrs. total. Widescreen; Soundtrack: English.
