The old Guy De Maupassant story The Devil would seem to be the springboard for the Italian-made Leap Into the Void. Michel Piccoli plays an Italian jurist whose sister Anouk Aimee is a bit "light in the belfry". Piccoli entreats Michele Placido to convince the awkward Aimee to kill herself. The results are unexpected, and fascinating. As with most of his work, director Marco Bellocchio uses the seemingly petty problems of his bourgeois characters as a mirror of what is going on in society at large. Leap Into the Void was originally released as Salto nel Vuoto; both Michel Piccoli and Anouk Aimee won Best Acting awards at the 1980 Cannes Festival.
