His list of film noir credits was relatively short. He appeared in "He Ran All The Way," "Scene of the Crime," and "The Black Book" (also known as "The Reign of Terror").
While Lloyd was noted for his remarkable memory and storytelling skills, he really had little or nothing to say about "The Black Book" in which he played an opponent of Robespierre. The Anthony Mann film produced by Walter Wanger with sets designed by William Cameron Menzies, a script by Philip Yordan and Aeneas MacKenzie and cinematography by John Alton is a unique period drama about the French Revolution that plays like a film noir.
My own guess is that Lloyd may have only spent a few days on the picture and he simply forgot about it.
