"No one who worked on the film can remember any special anecdotes or problems concerning it," wrote biographer Frank Brady. "Welles has said, since the making of "The Stranger"—which he completed one day "before" schedule and "under" budget—that nothing in the film was his, this despite the fact that the unmistakable Wellesian moods, shadows, acute angles, and depth-of-focus shots are pervasive. Within the film is a second film, another Wellesian touch, consisting of snatches of documentary footage showing Nazi atrocities." "The Stranger" was the first commercial film to use documentary footage from the Nazi concentration camps.
