Name an early-80s Disney cloak-and-dagger flick with nary a child in the cast? Yes, it's Trenchcoat, starring Margot Kidder as a saucy wannabe Hammett who gets mixed up with drugs and shieks in a strange land and Robert Hays as the man she reluctantly falls for.
Not to be confused with Romancing The Stone (1984), in which Kathleen Turner stars as a saucy wannabe Hammett who gets mixed up with drugs and bad guys in a strange land with Michael Douglas as the man she reluctantly falls for. Michael Douglas is of course best known to MonsterVision fans as the son of Kirk Douglas, star of such fare as MonsterVision's Saturn 3 (with Farrah Fawcett and a nasty robot), The Fury, and Exorcist 3.
