There is an early 1970s movie entitled, The Outside Man, which stars Jean-Louis Trintignant (who sadly just passed away & is famous for A Man and a Woman, 1966 Academy Award Best Foreign Film,-GUYS-ALL. WOMEN love this film - as long as they are willing to read the subtitles. If they speak french you're putty in their hands). Anyway, the movie is full of car chases in the Venice area, canals and all. He was also the assassin in The French Connection.
