Joseph H. lewis was a great director who could do wonderful films with little money. Maybe that was why Columbia's president Harry Cohn gave him so much freedom to work. So Dark is the Night is an almost noir entry about a French detective on vacation in a little town near Paris who investigates some murders which he was somehow involved. A short and objective cheap movie that does not hide the director's talent and gives Steve Geray a great role. People who want to make unexpensive movies should know this gem.
