Dial M for Murder

This is a brilliant movie I came across last weekend. Its an Alfred Hitchcock movie. Needless to say, it has an ingenius plot and great performances.
Typical mysteries, start with a murder and then the detective investigating the same. Some of these type of stories, keep you guessing who the murderer is till the end. Some suggest who the murderer is, but you cannot decide the method and the motive, since these facts are concealed from the viewer till the end.
This is just what is not an AF movie. Here, all the facts are right in front of the viewer. The plot is discussed with the viewer in the loop. The execution of the plan is also shown to the viewer, without concealing anything whatsoever. What your job as a viewing detective is, it is to deduce how the murder was carried out and determine the scheming mind, not using what you know, but using all the facts placed before you on the scene of the murder.
The directions is awesome. The performances are outstanding. It is a gem of a movie and a masterpiece of direction. It is a must watch!
