Diaboliquement Votre (1967)

Synopsis
In his last film effort (he was killed in a car accident shortly after its completion), veteran French filmmaker Julien Duvivier manages to spin gold from dross in Diabolically Yours. Alain Delon stars as an amnesiac, unable to remember he is man of wealth, or where he keeps his wealth. The doctors are flummoxed by Delon's total blackout. On the other hand, Delon's wife Senta Berger doesn't believe it, nor does the family's best friend. This fitfully entertaining puzzler succeeds in leading the audience--and the characters--down several garden paths. A French/Italian/German coproduction, Diabolically Yours was originally titled Diaboliquement Votre. ~ Hal Erickson, All Movie Guide
