As far as actors go, Jack Klugman is the MVP of "The Twilight Zone." He starred in four episodes, all of them classics. But this Season One gem is the least talked about and (possibly) the most impactful. In "A Passage for Trumpet," Klugman plays Joey, a washed up alcoholic jazz musician who, after attempting suicide (by jumping in front of a truck), goes on a spiritual odyssey to reclaim his verve for life.
There's no real twist, per se, just a thoughtful rumination on humanity and mortality, rendered in a classic, almost Kapra-esque fashion. Klugman is, of course, peerless, as is the moving script by Serling and the direction by Don Medford, which features one of the coolest practical effects of the entire series. Few episodes were ever this hopeful.
