ZZ Top released “Eliminator” in 1983 and Chevy Chase released “Fletch” in 1985. Both are period pieces (cue the synthesizers). Both are also, respectively, the greatest work of a talented and prolific rock band and greatest work of a talented and prolific actor (“Caddyshack” notwithstanding). Amazingly, “Fletch” is able to have a coherent plot (investigative reporter Chase uncovers a bigger story than he bargained for) and still make room for an enormous amount of Chevy schtick. John Cocktoastin. The Lakers fantasy sequence. Everybody in the movie seems to be having fun, even the bad guys. I had fun watching it.
