Il fantasma di Londra

The best way I can think to describe this movie is: suppose a group of German film makers snuck onto the deserted set of a Man From U.N.C.L.E. episode and made a movie there.

The only thing this movie has going for it is the sets. A fireplace where the mantle in front rises up to reveal a hidden doorway, a villain's lair with giant water tank holding large turtles, alligators (or maybe crocodiles) snapping at and eating anything tossed to them and a swimming pool with below surface level viewing windows.

Maybe this thing made sense in it's original language.
