In a TV film about the film Casablanca, Kren is meant to read aloud three letters that Groucho Marx wrote to Warner Bros., because they wanted to take legal action against him over A Night in Casablanca. The recorded material could not be used on television and was meant to be destroyed. Kren found it and showed it uncut with its repetitions.
