Part of the NBC Wednesday Night Mystery Movie.
Widmark had agreed to do his first (and it turned out, only) TV series shortly after finishing "Vanished," the four hour TV movie that marked his television dramatic debut. Originally, Widmark was to star in a series based on his second TV film, "Brock's Last Case," in which he played a NYC detective who retires to a farm in California. NBC, the network for whom Universal was producing the show, had second thoughts about the concept, and instead asked Widmark to reprise "Madigan," the 1968 theatrical film that earned strong ratings when it was broadcast on the network in 1969. Widmark agreed providing half the shows were filmed in Europe.
