I went to the Strand Theater in Dover (NH) to see this movie when it came out back in 2005, and I remembered enjoying it quite a bit. And the Writer/Director, Shane Black, went on to direct the best (imho) Iron Man movie, that would be number three (your mileage may vary, but shouldn't). (Black also had an impressive run of writing action movies, see his IMDB résumé.)
I was under the impression, a few years back, that eventually any movie or TV show that ever was would be available to stream via some provider, at a reasonable monthly fee. David Janssen's short-lived private eye classic Harry O. The goofy comedy The Big Bus. Ken Russel's surrealistic musical comedy The Boy Friend. And …
Well, wasn't I was a starry-eyed optimist. If anything, trends seem to be going the other way, with services pulling shows and movies off their lists. And adding advertising to what's left.
But I wanted to see this bad enough to send Amazon an extra $3.99.
Robert Downey, Jr. plays Harry, a small-time New York crook who, by sheer accident, gets hired for a movie role out in LA. There he meets Gay Perry (Val Kilmer) who is supposed to be tutoring him for his part. And is reunited with a childhood acquaintance, Harmony (Michelle Monaghan), who's looking to make her mark in Hollywood as well. But pretty soon, Perry and Harry accidentally witness a murder while on a stakeout.
The plot is very complicated, self-concious, and ludicrous. And a lot of fun. Downey and Kilmer are great.
Nice touch: this noirish movie has acts with titles stolen drawn from Raymond Chandler books.
