Enjoyable krimi film; I really need to see more of these. A man in black strangles people and threatens an old man to reveal where the diamonds he stole are hidden. The old man's niece is a journalist, so naturally she becomes interested in the story of the strangler (without knowing how her uncle is involved) and the police also investigate.

Reasonable suspects include the old man's strange butler, and the eccentric Lord of the castle, among others.

Despite the title, the "Strangler" also carves an "M" into his victims' foreheads and decapitates two of them, one of them right before our eyes.

As with the last Wallace krimi I watched, this one has people looking through peepholes, and secret passages.

Watched Alpha's DVD of this; no complaints.

The problems are. 1) the comedy relief, is the wacky mustache-bird- recording character and if that isn't enough the spunky little kid that sometimes acts as his sidekick. 2nd problem is the music score, all electronic though not much of it, but it is also used mostly for comic relief which is not early electronic music's strong point. Some other sounds are comically dated now--though music for these German films is frankly usually pretty bad--awful non stop squealing rock/jazz so this film's lack of music is mostly a good thing but the comic electronic burbs and beeps are hard to get over and distracting, but, like I say at least there isn't a lot of music. And the comic relief also doesn't overwhelm the plot but does pop up just when you least need it.

The last deficit is that just past the half way point in the movie briefly stops making sense, this is another problem with these films there are so many characters that you lose track at some point. This film has a series of car ride sequences with the cops talking about various suspects and it just becomes a blur, this one holds up longer than most though plot wise and it does get back on track before the ending.

The Alpha DVD is full frame and things are obviously cropped but the print is in decent shape, just turn down the brightness a little.

For a Strangler film the strangler does almost as much beheading as strangling, this is a good thing and it adds variety and strangling can be pretty dull on film, the spfx are pretty good especially one on screen decapitation. There is one awful mechanical bird but is part of the equally bad comic relief and only appears twice and very briefly.

The film moves well and "attacks" come pretty regularly and the ending is very well photographed in a foggy swamp and forest. The dubbing is actually not too bad which helps the movie too. There is a very clever hiding place for the diamonds too.

So prepare yourself for the bads and enjoy the goods and this film is well worth the time to watch it.

Despite the noticeable absence of series regulars Eddie Arent and Klaus Kinski, this is another solid entry in the long-running Edgar Wallace (or in this case, son Bryan) krimi series, and probably the most action-packed. Unlike the playfully gimmicky Alfred Vohrer, director Harald Reinl (an acknowledged Fritz Lang disciple) preferred to play his material straight, emphasising action and violence. The proceedings are highlighted by surprisingly gruesome assaults and murders (decapitation being a specialty here), but to his credit, Reinl filled in the edges with imaginative touches, eccentric behaviour by oddball characters, and quirky humour (the knock-out by moosehead would have pleased Vohrer immensely). The cheekiest Langian homage is the M inscribed on the victims' foreheads, but there are plenty of other visual and thematic tropes that smack of the master's influence (it was Reinl who took over Lang's Mabuse franchise at about the same time as this picture). For instance, one minor character, a henpecked clerk, insists that he could definitely tell that the suspect who phoned him was a blonde by her voice (wink-wink), prompting a withering look from his wife. The moody b&w cinematography is often striking, and the creepy modernist score is effective and memorable. The director's statuesque wife and regular leading lady, Karin Dor, is disappointingly mousy in her role, but Ingmar Zeisberg steals the show as a sultry, unnatural-blonde barmaid at a sleazy Soho cabaret who leads a double life. Only the final revelation of the murderer is a bit of letdown, but that was par for the course.
