I think that people miss the historical aspect of this movie. It was 1960 and Hollywood was just figuring out how to make a "real" and gritty crime drama. Yes the film is bizarre - Father Knows Best meets The Wild Ones or The Blackboard Jungle. The average scriptwriter probably wasn't real familiar with the daily life of street criminals and the language would have gone right over their head.But the movie shows the by 1960 crime was becoming more of a concern for the average middle class American family. People were starting to learn that their safe, secure little worlds, weren't and that the crime of the "lower class" neighborhoods was moving into their daily life.By 1970 middle class America would be much sadder and wiser, but this film shows that crime was a concern in during the good old days of President Ike.Basically it's an interesting look at the time.It's one of the few older movies I've come across in which there is a reference to a character, even a villain, using Cocaine. Yes the thugs are too clean and they don't look like they smell. As a cop I can tell you the one thing that movies don't convey is the smell of that world. How can they?The only movie that I can think of that came the closest was "Training Day".Don't compare this movie to modern productions, it isn't fair. Overacting and melodramatic scripts were normal and expected. Just watch shows like Star Trek,Route 66, The Big Valley and The Fugitive. Those shows were over the top by our standards, but not back then.It isn't that bad.

It's quite possible that not a single motive or action in this entire film resembles anything human. Look at what you can learn from it: You receive a phone call in a supermarket that threatens your family? Don't hesitate to let your wife go off by herself to get "one last thing." One of your kids is shot in the schoolyard by a coke-crazed gang member? By all means let your other kid finish out the school day. And above all, try to involve yourself in one of the most ineptly choreographed climactic fight sequences in the history of cinema. There are literally hundreds of stroke-inducing moments in this truly moronic, dime store Cinemascope mess. "Key Witness" seems to have sprung from some kind of weirdly fastidious "social consciousness" of its period, as if it were the philosophical love child of Ronald-Reagan liberals. But whatever its context, the film now appears to have been constructed by Martians with powerful telescopes.

One of the great bad movies of all time with an over-the-top performance from Dennis Hopper which he wouldn't top in outrageousness until "Blue Velvet."Sample dialogue:Dennis Hopper: "You're real a talkin' talker, right? You know what happens to talkin' talkers who talk, Talker?"Jeffery Hunter: "What are you talking about?"And no, its not supposed to be a comedy--its supposed to be a hip, hardcore juvenile delinquent thriller. But it's hilarious!Find it at all costs!

I really enjoyed this film. However, I enjoy all films of this particular genre. Black and whites film from the late 1950's/early 1960's. Plenty of hip looking individuals with snappy lingo. The detectives wear hats and the punks are bad news. It reminds me of "Blackboard Jungle" or some Stanley Kramer film.The story is about doing the right thing, even when the wrong thing is much easier to do. Moreover, you get to see a young Dennis Hopper do his early version of Frank Booth from "Blue Velvet." Good stuff in a retro kind of way.
