The Asphalt Jungle is not a true spinoff from the movie of the same name, sharing only the title and the studio (MGM). As it happened, it was a summer replacement series in 1961 and lasted just 13 weeks when it could've gone longer, but for the fact that it was just another crime drama.
Jack Warden and William Smith headlined a promising ensemble cast, and would each go on to greater successes. Seeing this show for the first time via YouTube, I can see just what the problem was. As noted, it really had 0 to do with the movie, and instead focused on the same subject matter as other crime shows, with a few exceptions, one of which being a case study, if you will, on the American Nazi Party, as demonstrated in the episode, "The Scott Machine", with guest stars Robert Vaughn and John Astin.
