Sadly Over-hyped

n my opinion it was a great movie with some interesting elements, even though having some plot holes and the ending probably was just too messy and crammed together, but still fun to watch and not your casual movie that is similar to all other ones.

Watch something else. There are very few redeeming qualities to this film.

This film is so real. It treats its characters with so much care and sensitivity.

This is one of the good german b/w thrillers from the 60'ies. It has a nice plot and features a lot of german movie and tv stars of this time like Walter Rilla, Joseph Offenbach, Günther Ungeheuer, Monika Peitsch and many others. "Vier Schlüssel" reminds of the sixties tv series "Stahlnetz" which was made by the same director Jürgen Roland. If you liked "Stahlnetz" and other german b/w thrillers chances are good that you will also enjoy this one.
