Ten Days' Wonder

In this ponderous French mystery-drama, based on an Ellery Queen story, blackmail would seem to be the least of the problems of Charles (Anthony Perkins). His adoptive father Theo (Orson Welles) has a madwoman for a mother, and a gorgeous woman of Charles' age (Marlene Jobert) for a wife. In fact, Charles is deeply attracted to her. In addition, his father encourages the whole family to dress in '20s clothing, which makes them all feel out of place. (allmovie.com)
