The Devil Is a Woman (1935) review

Soldier Antonio (Cesar Romero) locks eyes with the notorious singer/entertainer Concha Perez (Marlene Dietrich) during a festival in Spain and is mystified, but before he meets up with her he sits down with Captain Pasqualito (Lionel Atwill), who tells him about how he tried to court Concha in the past and she toyed with him, ruined his reputation and took all of his money.  Handsomely shot (by Von Sternberg himself) and quite evocative - all those streamers and masks and confetti! - it's the last film Marlene and the director made together (with a script by John Dos Passos, of all people) and quite a doozy, as she changes her mind and mood whenever she feels like it and her suitors can't help but follow her around as if they're under her spell.  It doesn't hurt that it's the great Marlene pulling the strings: as we now know from her personal life and "unending string of affairs" (per Wikipedia), she usually got what she wanted, and left when she felt like it.
