Since it was made in 1965, we can assume that Casanova '70 is set five years in the future. Marcello Mastroianni stars as the modern incarnation of the legendary lover. This Casanova is a NATO officer who is sexually aroused only when danger threatens. And that's about all there is to it, except to add that the ladies-Virna Lisi in particular-are gorgeous. Director Mario Monicelli cowrote the screenplay, which was nominated for an Academy Award.
