A superb thriller, this riveting nail biter is chock full of surprises that literally shock a few of the eight and might shock viewers as they get more intrigued by the goings on in this variation of Agatha Christie's "Ten Little Indians". Eight people of varying moralities are gathered together for a lavish party at a stranger's home where the staff knows nothing of their employer, and no host seems to be around. As they are about to leave, the radio goes on and a booming voice warns them about the impending dangers they face should they decide to leave, indicating that only the strong will survive, and that most of them will perish due to their immoral characters. The battle of wills between the apparently evil guests and the sinister evil of the host becomes drawn, with one guest getting their due right at the stroke of 11, and several others forced through panic into doing things they know might either shock them right then and there or send them to the electric chair over crimes they commit in their efforts to escape.The set up of this film is a mixture of gripping horror and light comedy, particularly through clumsy butler Vince Barnett who steals every moment that he is on screen, particularly in a drunk scene in a wine closet hidden within the elaborate kitchen setting. The cast of characters might not be all star players from Columbia's contract players, but they each get minutes to shine as they share their character (or lack of it) with other members of the party and the audience. Moments of panic leads to moments of intensity for the office, so this mystery/thriller gets to include genuine moments of terror as well, making this a combo mystery/horror film that keeps you guessing right up until the end. Donald Cook, Genevieve Tobin, Hardie Albright and Edward Ellis are the top billed guests, with Samuel S. Hinds and Nella Walker also recognizable for savvy classic movie watchers. The script, though, is the true star, intelligently written and sophisticated in its way of developing the terrors that go on right up until the end.

Easy to be mistaken for a variation on Agatha Christie's famous "Ten Little Indians", this largely unknown movie is more like an inspiration! (it was based on a book written 9 years earlier than Christie's book). Beyond the surefire premise (8 people trapped in a penthouse by an unseen host, killed one by one based on their past sins), it's tightly scripted, and benefits from the absence of law enforcement officials, and little comic relief (the assistant butler). There is even character development! Roy William Neill's sprightly direction never lets you feel claustrophobic (well, not more claustrophobic than you're supposed to feel anyway....),and the actors, although not top-drawer names, manage to differentiate their characters sufficiently. If there is one thing I can say against the movie, it's that it cheats - partly: two vital clues are named at the unmasking of the host, but if you watch the movie again, only one of them is true! *** out of 4.

The best thing about this movie is its basic premise - eight people are invited by an unknown person to attend a party in an Art Deco designed penthouse. Once there, through a radio, they are informed by the "ninth guest" that it is impossible for them to leave because all the exits have been electrified and the phones disabled. The radio voice then informs them that each one of the guests will die. And one by one, the guests do start to die. It is fascinating how reminiscent this plot is of Agatha Christie's 'And Then There Were None,' her most famous book published five years after this movie. Of course, her book and the films later based on it are far superior to this movie. The two leads, Donald Cook and Genvieve Tobin really aren't given much to do and their characters are pretty bland. Even so, the 'Ninth Guest' is intriguing and sufficiently entertaining to be worth a watch.

This movie just became available on YouTube. This is an adaptation of the book The Invisible Guest, and follows a similar plot to Agatha Christie's Ten Little Indians, while predating it by almost ten years. The plot is simple - people have been invited to a party by an unknown host, and are being killed off for their 'crimes.' In an interesting twist on the genre, this story is set in a modern penthouse apartment rather than a dark old house. And while the 'second butler' is introduced for laughs, he is on the screen for a mercifully short time.Don't expect a lot here - I gave it a '6', thinking it's just above neutral. I did watch it to the end, but I wasn't always engaged, and the clunky romance element didn't help it much. Also in its favor, in a negative sense, there was no bumbling police to spoil what there is of drama. Worth a watch for those who like the genre, but not something you'll watch a second time.
