A Gathering of Eagles stars Rock Hudson as a colonel in the peacetime Strategic Air Command. His devotion to his duty as a wing commander takes a toll on his men, his marriage, and his own well-being. It is to Hudson's credit that he was willing to put his image on the line with this essentially unsympathetic characterization, and a tribute to his underrated ability as an actor that he compels us to care for him. Popular British leading lady Mary Peach makes a rare Hollywood appearance as Hudson's English wife. An unexpected bonus to A Gathering of Eagles is a semicomic musical piece, "The SAC Song," by dilettante satirist Tom Lehrer.
