"The Flame" is a dark but disappointingly routine melodrama of the seen-it-a-million-times-before variety. A French nurse, in cahoots with her sleazy American lover, agrees to marry his ailing half-brother in order to gain his wealth. Guess what -- she begins to fall for the bore (who whiles away the hours playing dirges on his Hammond organ).John Auer was one of the more talented directors working in the B-movie mill of the 40s, and he injects the picture with enough visual panache to give it a professional veneer and subtle moodiness. But what can you do with this cast from hell -- particularly Vera Ralston, at her most wooden (her voice-over narration is practically indecipherable).A couple of reels into the film, things briefly perk up when a young Broderick Crawford unexpectedly slides into the narrative as a dour potential blackmailer who gets wise to the scam. Even better, his sometime girlfriend is a sexy cabaret performer played by the always fascinating Constance Dowling -- her Gilda-style song and dance routine gives Auer a chance to show his licks. But the brittleness all dissolves pretty quickly into some very unwelcome sentimentality towards the end.
