In an attempt to cash in on the success of Universal's horror films Majestic Pictures hired several popular actors from the current genre and put them in this effort that (realistically speaking) is nowhere near as good. With that, this is still worth everyone's time and it's a heck of a lot of fun to view and in my opinion it's better than most of what is supposed to pass nowadays as horror! Story takes place in the small German town of Klineschloss where the bodies have been piling up completely drained of blood and with suspicious puncture marks. Burgermister Gustave Schoen (Lionel Belmore) shouts "It's Vampires" but the local police chief Karl Brettschneider (Melvyn Douglas) thinks it's a madman who's responsible and he vows to catch him.
*****SPOILER ALERT***** The Burgermeister and most of the towns folk think that the local kook Herman Glieb (Dwight Frye) who loves bats and frequently talks to them is the one they are looking for and they chase him until he falls to his death in a cave. The one who is responsible for the killings is Dr. Otto von Niemann (Lionel Atwill) who has created a new form of tissue mass that feeds on blood and he accomplishes this by having some sort of mind control over his servant Emil (Robert Frazer) who goes out at night to collect the blood. Dr. Otto has a pretty assistant named Ruth Bertin (Fay Wray) and an annoying aunt named Gussie (Maude Eburne) but they have no clue what he's up to but Karl eventually become suspicious when one of the murders takes place after Herman's death.
Frank R. Strayer was never confused with being James Whale but he was a pretty competent director who ended up directing most of the "Blondie" films in that series and with this film he uses the same sets from "The Old Dark House" which was also filmed at Universal. I'm the first to admit that this film is downright clumsy at times but it's practically impossible to resist a film that has a cast like this including Frye who is pretty much doing his Renfield role only this time he befriends bats and strokes them and keeps them in his pocket for safe keeping! One thing that just doesn't make sense is the mind control that Dr. Otto has over Emil as the film never explains this and I had a strong sense that this was some sort of nod to "The Cabinet of Dr. Caligari" but on the other hand it's probably just the weakest part of the script. There are a few other tidbits that I noticed including the chase of Frye to the big caves which is obviously an early shot of the infamous Bronson Canyon where numerous other films have been made and also Wray's brown hair which is her true color. True horror film fans will appreciate this more than others but I think this is a fun film to view for everyone and with a cast as attractive as this it's well worth a look.

(various spoilers follow)
Gene Kelly. Not Georges Guetary, who is sometimes criticized for being too young and un-French. Not Leslie Caron, who is sometimes criticized for her very green performance. Not even Oscar Levant, who more often than not annoys the dickens out of me.
No, it would definitely be Gene Kelly. There's something about his screen persona that's too ambitious and focused for him to be convincing as a penniless artist in Paris, content to put off facing the critics indefinitely, frolicking with little kids and old ladies and painting in the streets. That's what made him so effective in SINGIN' IN THE RAIN and other movies where he played ambitious, focused characters. Jerry Mulligan is in some ways a cousin to Tommy Albright in BRIGADOON, another Lerner story with Kelly miscast as an American at loose ends who falls in love with a picturesque European place and an innocent female who embodies its virtues.
Except that Jerry isn't as likeable as even poor dazed Tommy. That's another galling thing about this film. Jerry is sometimes a cad to Milo, and even worse to Lise. When he first sees the latter at a club, he pulls a dirty trick to get her to dance with him. When she sits down again he pulls an even dirtier trick to get her phone number. When he calls her the next day she hangs up on him, which he takes as a cue to drop in at her workplace. And throughout all this it's obvious she wants NOTHING to do with him. When she starts laughing at his jokes in the perfume shop, it's about as believable as Milo's interest in his paintings. Sure he's good-looking and playful, but why should that sway her when she's got Henri, who seems like a gentleman to boot?
Admittedly it comes off so distasteful partly because of the actress. If a role like Lise was played by, say, Judy Garland, she would shower Jerry with indignant insults and glares. If she was played by Cyd Charisse, one would admire his guts. But when she's played by first-timer Leslie Caron she looks and acts like a shy, vulnerable teenager, and as a result Jerry just seems like a creep. And why DID they choose these other actors (though personally I'd rather they'd solved things by changing the lead) when the whole story hinges on the romance of these two young poor sweethearts disentangling themselves from their loveless commitments to older rich people? Not only is Gene Kelly a few years above Guetary and Foch, he's old enough to be Caron's father.
In short I think it all would have been improved by casting some young comedic-relief type dancer as Jerry, the kind that usually turned up in musical supporting roles...e.g. Ray MacDonald in GOOD NEWS or Bobby Van in SMALL TOWN GIRL. Maybe not them necessarily but someone LIKE them. Someone who could have chased Lise and made it seem harmlessly playful; someone who would have appeared genuinely happy living in that Chaplinesque hole-in-the-wall; someone whose humor and naivete would have contrasted better with Oscar Levant's sarcastic grumpiness. It probably also would have made the ballet seem less ponderous. And it might have provided a voice that could sing Gershwin better.
All this may give the impression that I don't like Gene Kelly. I do like him. He was terrific in most of his films, just not this one (well, and a few others). I don't despise AAIP itself, either; it has good points, like the art direction. And Leslie Caron, who despite her inexperience is rather charming, and really does look like she just stepped out of a painting. Georges Guetary does a fine job and his "Stairway to Paradise" is my favorite number in the movie. Nina Foch is beautiful and touching and should have ended up with SOMEBODY. But not Jerry Mulligan. I wouldn't wish that on her.
