This movie, “Midnight Cop” (1988), also known as "Killing Blue," feels like a Berlin version of "Dirty Harry"—though it’s not quite that good—and suffers from some really jarring editing. It's a detective story set in a bleak Berlin, featuring an older, world-weary detective (Armin Mueller-Stahl) working on a murder case alongside a younger partner (Julia Kent) who still believes in doing things the right way. Michael York is the district attorney, Frank Stallone portrays a drug dealer, and Morgan Fairchild appears as a prostitute. Despite its flaws, there's enough here to hold your attention if you’re into this kind of thing. The editing really holds it back; I'm not sure whether that was a stylistic choice popular in Europe at the time, an attempt at something experimental, or just plain bad filmmaking. If you can get past the uneven rhythm, there are some good parts—Julia Kent and Morgan Fairchild both stand out, along with a few other attractive performers. The soundtrack is also noteworthy, incorporating “Whiter Shade of Pale” among its jazzy selections, and even manages to inject some humor into what's otherwise a dark story. It’s essentially an amalgamation of 80s European films reminiscent of "Dirty Harry," "The Organization," "Death Wish," and "Lantana"—though it doesn’t have their polish. I would suggest using subtitles, as the dialogue is frequently difficult to understand, particularly when spoken by Mueller-Stahl. The actors speak English (some of which seems to be dubbed), but you're meant to assume they are speaking German. The film clocks in at around 1 hour and 35 to 40 minutes and was filmed in West Berlin, though the scenery isn’t pretty; the urban photography is consistently dark, gray, industrial, and depressing—which suits the overall tone. GRADE: C+/B-
