As far as movie themes go, Harold Faltermeyer's "Fletch" has to have one of the most memorable synth lines ever. Although not as successful as his Axel F theme, the same appeal is present. This has to be one of my favorite collaborations ever. It's right up there with Jan Hammer and Tangerine Dream's best soundtrack work. Chevy Chase owns this persona, the role obviously tailor made for him. The score also suits the movie perfectly. I've watched Fletch countless times and it never gets old for me. It reminds me of the good ol' days, when Chevy Chase was still funny. Here are 3 different versions of the main theme found on the official soundtrack.
