The title of this French crime meller translates into The Gun Moll. Eddie Constantine makes the first of several appearances as Lemmy Caution, the two-fisted American government agent created by novelist Peter Cheney. In this outing, Lemmy is dispatched to Casablanca, there to put the kibosh on a gold-hijacking operation. His job is made easier when he wins gun moll Carlotta (Dominique Wilms) over to his side. At 105 minutes, the action flags on occasion in La Mome vert de Gris. Still, the film was successful enough to spawn a whole series of "Lemmy Caution" adventures, including Jean-Luc Goddard's novelle vague fantasy Alphaville (1966).
