The Greatest Mysteries of Cinema

Whether the mystery is
"whodunit?"
"did he really do it?"
"who is behind it all?"
"what happened here?"
"where is she?"
"who opened the Chamber of Secrets?"
"whats going on in this creepy town?"
"what's going on... everywhere???"
or just "what is... what???"
these movies will keep you guessing 'til the end! Or... the third act, probably.
