Directed by Don Siegel who had a foot firmly planted in classic Hollywood and who was also a trailblazer in modernizing American action films, "Madigan" serves the perfect bridge between the two. Co-written by Abraham Polonsky, who'd previously been on the Hollywood Blacklist for refusing to testify before the House Un-American Activities Committee, the film follows two different NYPD police officers. One is Madigan, a tough no-nonsense detective played by Richard Widmark trying to catch a killer, and the other is the straight-arrow police commissioner, Henry Fonda, who's balancing justice, politics, and an extra-marital affair. The film was based on a book titled "The Commissioner" and Fonda's character was the original focus of the story, but the producers instead changed the focus to Widmark's Madigan character, so the film unfortunately ends up a an odd combination of two different stories. Both Fonda and Widmark's stories involve them having to balance their work-life and home-life, but neither of those story elements seemed all that interesting. The most interesting part of the story concerned Widmark and his partner, Harry Guardino, on the trail of criminal Steve Ihnat. Watching Widmark and Guardino push the boundaries of acceptable law enforcement in their investigation makes this film an interesting bridge to director Don Siegel's controversial and highly influential vigilante cop film "Dirty Harry" he'd make a few years later. Siegel also makes great use of NYC locations that give ether film added grit and realism, much like we'd later see in William Friedkin's "The French Connection" and Siegel's use of San Francisco in "Dirty Harry." Siegel also skillfully demonstrates his own directional action sequences chops with a memorable showdown in the film's finale, which features with three characters in tight quarters, all with John Woo-style double-fisted pistols in each hand. Overall, "Madigan" features an old style police detective story (with a nice plot nod to Kurosawa's "Stray Dog") that abandons the stylistic German Expressionist roots of American film noir and instead takes the genre into new more realistic and gritty of territory, even if those stronger elements get somewhat undone by dull and unoriginal subplots involving the marital lives of Madigan and the commissioner.
