The premise held so much promise—a sweeping cinematic scope directed by Andrew V. McLaglen and featuring a roster of well-known actors tackling a narrative centered on wartime deception and bravery. However, the final product falls short. Richard Burton portrays a volatile sergeant named "Steiner," struggling with an inconsistent German accent, who becomes entangled in a plot orchestrated by "Von Stransky" (Helmut Griem), his personal adversary, under the orders of the manipulative general "Hofmann" (Curd Jürgens). Steiner is tasked with attempting to establish some form of agreement with advancing Allied forces amidst internal efforts within the Wehrmacht to remove their leader. During this mission, he provides assistance to American colonel “Rogers” (Robert Mitchum), but whether that will be sufficient to persuade the doubtful "Gen. Webster" (Rod Steiger) that the overture is genuine—or simply a tactic to gain time, or both—remains unclear. Regrettably, neither Burton nor Mitchum deliver performances up to their usual standards. While the director attempts to maintain momentum through action sequences and battle scenes, the film suffers from numerous underdeveloped storylines, a script that feels overwritten, and characters who lack depth, hindering its overall coherence and ability to captivate. Rod Steiger’s appearances are too infrequent to have much impact, and after roughly an hour of viewing, it felt like I was experiencing fragments of several other, superior WWII films blended together. It seems likely everyone involved appreciated the financial benefit, but as a film, it's rather disheartening.
