Many consider this 1932 film the height of sexual sophistication in pre-Production Code Hollywood. Lubitsch doesn't apologize for his protagonists being thieves and cheats; the audience is rooting for them for precisely those reasons, hoping that they'll get away with their deceptions. Lubitsch famously quipped about this film, which takes place in Venice and Paris: "I've been to Paris, France and I've been to Paris, Paramount. Paris, Paramount is better." The link below goes to the New York Observer, which has an appreciation of Lubitsch by Peter Bogdanovich. He weighs in on Lubitsch's contribution to American cinema, and the style of acting in Lubitsch films.
