The first film to receive 7 Academy Award nominations without receiving a Best Picture nomination.
To promote the film Joan of Arc (1948), the studio placed an eight-story-high figure of her in white plastic armor in New York City's Times Square, at a cost of $75,000.
According to some biographies of Ingrid Bergman, Howard Hughes saved her from possible injury during a visit to the set when she fell off her horse. He caught her, but rather awkwardly, with one hand firmly on her crotch. Hughes made sure no photographs of the incident were taken (or survived).
The film was not really a commercial success upon release, but only partly due to RKO's poor publicity campaign (which producer Walter Wanger blamed on then-RKO president Howard Hughes). Audiences stayed away from the film when Ingrid Bergman's affair with director Roberto Rossellini was revealed while the movie was in release, because they considered it blasphemous for an adulterous woman to be playing a saint.
