Plot so thin, it passes unnoticed.

Memorable, crazy movie

Too much about the plot just didn't add up, the writing was bad, some of the scenes were cringey and awkward,

Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.

This is certainly one of THE classic 'old mansion murder mysteries' that were so popular in the 30s; and it can contend with most of the very best of them. A great challenge for every mystery fan who likes to guess the murderer, because the plot takes so many turns and twists that it's really hard to follow even for a 'murder expert'! The settings are excellent, following the classic scheme of the old, elegant but somehow frightening isolated country house, with solid wooden stairs, long dark corridors with knight's armors in every corner, distinguished old-fashioned furniture - and a dark room with an old DARK mystery...The cast is magnificent, headed by mystery expert Lionel Atwill, and beautiful Gloria Stuart (who had also played in "The Old Dark House" a year before) as the object of desire for no less than three young men; Edward Arnold, well-known to friends of more down-to-earth gangster movies and comedies, as the blunt detective, Paul Lukas as the suave foreign 'officer and gentleman' - even every bit part was casted just perfectly! In my opinion, an absolute 'must' for any fan of the classic mysteries of the 30s - and a good opportunity for others, who are not too familiar yet with the genre, to get to know it WELL and at its BEST!

I last saw this film 30 years ago, remembering only the final chase down the innumerable underground stairs. Seeing it again I see why that's all I remembered. There is no feeling of suspense. The lighting is bright and uninteresting, the directing bland, the actors simply walking through their roles with some of them being downright amateurish. Lionel Atwill shows not a trace of evil intent, immediately removing him as a red herring. The three suitors have no chemistry with Gloria Stuart or for that matter with each other. The only actor that adds some mystery to the film is Robert Barrat as the butler. The under-appreciated Barrat could play anything believably - judge, madman, sophisticated jewel thief.A few comments about the accuracy of previous reviewers' statements. The Swan Lake title theme was used for Dracula but amended for The Mummy and as such used for Murders in the Rue Morgue and Blue Room. A short studio composed prologue was added as the faces of the pyramid rotated.No sets from The Old Dark House were used in Secret of the Blue Room. It is possible that some details such as wood paneling and stair case portions were re-used.The lowest staircase is identified as the cellar from Frankenstein. This is problematic. The Frankenstein set had a solid floor; Blue Room had flowing water. This same set with rushing water was rented for White Zombie, intimating that it was new or substantially rebuilt for an unknown Universal film subsequent to Frankenstein. Blue Room also had a stone arch in the foreground, lacking in the Frankenstein cellar.Paul Lukas was not imitating Bela Lugosi; he had an identical accent.

Considering it's age, a pretty good old dark house/castle movie The acting is a bit stilted, as one would expect for the year it was made This is a locked room mystery, in which multiple people have been/are killed in the castle 'blue room' The film starts out slow with a love quadrangle (!) and a full length song, but gets going after that, The earlier mystery that the plot is based on is never explained, and leaves us wondering at the end, Paul Lukas plays with a strange Bela Lugosi accent, which i found annoying, but i got used to it eventually, Worth watching for genre fans, but it would have been better if they waited a few years to make it

Three men all in love with the same woman decide to spend the night in the cursed "blue" room where tragedy strikes who ever spends the night. Of course tragedy again strikes and the police are called into solve the crime.Grand Universal mystery thriller suffers from having been remade both officially and unofficially over the years. The film itself is a remake of an earlier German film so I guess turn about is fair play.Feeling more like an old friend rather than a griping thriller this film is a good little mystery. Odds are you'll know whats going on, but you won't mind since the cast is the real reason to see this. Paul Lukas is a dashing military man, Lionel Atwill is the owner of the cursed house, Gloria Stewart is the woman in question and Edward Arnold is the detective called in to solve the crime. They are all aided by a strong supporting cast of Universal studio regulars.This is one to make an effort to see especially if you're a fan of good, if familiar, mysteries.7 out of 10 due to the passage of time and the multiple remakes.
