...a tutte le auto della polizia (The Maniac Responsible)

As you can probably tell from the poster, Mario Caiano's ...a tutte le auto della polizia is a poliziesco/giallo hybrid along the lines of Dallamano's La Polizia chiede aiuto. Some people might find this a tad slow-moving for a giallo (since the killer doesn't start dispatching of witnesses until quite late in the film), but hopefully that won't put anybody off. Great direction by Caiano and excellent performances by Enrico Maria Salerno and Antonio Sabato.
I was fortunate enough to be able to see this through an excellent fan subbed dvd made by Martin at the Lovelockandload forums. I think that it's an excellent film and I've already revisited it a couple of times since I got this earlier this year.

No info on the poster artist.

L'Occhio nel labirinto (Eye in the Labyrinth)

Julia (Rosemary Dexter) dreams that her psychiatrist boyfriend Lucas is stabbed to death. The next day he is nowhere to be found. All traces lead to the small Mediterranean village Maracudi, where Gerda Hoffman (Alida Valli) lives with a variety of eccentrics, musicians and artists. Gerda claims never to have heard of Lucas but Julia soon finds evidence that he might have been at the villa after all…
Enjoyable giallo mostly set in and around a seaside villa (similar to that in La Settima Donna), but director Mario Caiano keep things moving at a brisk pace. Rosemary Dexter is a beautiful leading lady and Valli and Adolfo Celi provide great suppporting cast. Poster art by Symeoni.
