It’s our final 70s Columbo of the podcast! We’re saying farewell to the Lieutenant’s original decade with “Playback,” an episode featuring dazzling futuristic gadgetry, bowl haircuts and Gena Rowlands. Electronics executive Oskar Werner is on the verge of being fired by his mother-in-law. He kills dear old mom, then rigs his home’s elaborate security video setup so no one even discovers the murder, until he’s safely in alibi city, miles away. The gadget-happy killer’s plan even has Columbo stumped for what seems to be longer than usual, in an episode that also feels longer than usual. Dylan Meconis (The Long Con) is here to look through this one, which seemed to stay at a flat level of “just fine,” as well as speculate how a Columbo comic book series might work. In all, a nice edition of the podcast.
