Whodunit/Murder Mystery recommendations?

[iceblox]

I love Whodunits and Murder Mysteries, or even movies where there is a slick twist in the end, which makes me go "wow"..I practically grew up on Agatha Christie, and I love her work. The reason why I haven't just attempted to see every movie adaptation of hers is because I don't know how good they are.

Any good recommendations you can think of? Language doesn't matter, as long as there are subtitles, and of course the DVD is available or even a rip available to download somewhere (that's OK anyway, I'll do the hunting part).

Here are some of the movies which I've seen and liked:
Murder on the Orient Express (1974)
A Shot in the Dark (1964)
The Thin Man (1934)
Witness for the Prosecution (1957)
..there are also some Indian movies, but they are probably not known outside of India, so I won't mention them.

These are the movies which I've already planned to watch, so you can omit these from your recommendations:
Clue (1985)
Green for Danger (1946)
Murder by Death (1976)
Ten Little Indians (1965)
Kaasua, komisario Palmu! (1961) -------> I haven't found any available subs for this one yet.
Komisario Palmun erehdys (1960) -----> I haven't found any available subs for this one yet.

Thanks in advance!

Manhattan Murder Mystery

Are you into Giallo? In case you don't know what it is, it's Italian horror-based murder mystery. I personally prefer it much more than regular murder mystery, but everybody's different. Here are some recommendations:

"Blood and Black Lace" (Mario Bava, 1963)
"The Bird With Crystal Plumage" (Dario Argento, 1970)
"The Strange Vice of Mrs. Wardh" (Sergio Martino, 1971)
"Tale of the Scorpion" (Sergio Martino, 1971)
"All the Colors of the Dark" (Sergio Martino, 1972)
"Your Vice is a Locked Room and Only I Have the Key" (Sergio Martino, 1972)
"Twitch of the Death Nerve" (Mario Bava, 1971)
"Torso" aka. "The Body Bears Traces of Carnal Violence" (Sergio Martino, 1973)
"The Violent Professionals" (Sergio Martino, 1973)
"Deep Red" (Dario Argento, 1975)
"Suspiria" (Dario Argento, 1977)
"Tenebre" (Dario Argento, 1982)

If you are interested in viewing any of these titles (which I highly recommend as they are fantastic cinema), I recommend you check out "Deep Red" aka. "Profondo Rosso" first.
