Act of Violence (1948) - Warner Archive Collection

When two World War II veterans meet again--one a decorated war hero and successful, married businessman; the other permanently crippled and mentally deranged--the encounter will lead to a shocking Act of Violence. Frank Enly (Van Heflin) survived a German concentration camp to return home a hero and build a good life for himself. But when Joe Parkson (Robert Ryan) comes to town, Enly flees. Now, as his life and sanity rapidly unravel, is Enly really a lying traitor who sold the lives of fellow concentration camp inmates for his own survival as the mentally unstable Parkson claims, or is he a victim of survivor's guilt that has suddenly resurfaced with Parkson's return? And will the enmity between the two lead to murder in this acclaimed film noir thriller, from masterful director Fred Zinnemann.
