Lion's Den is a 1988 short film directed by Bryan Singer and John Ottman. It marks Singer's first film as a director. The film is about five men who meet up at their old hang-out spot (called the Lion's Den) after finishing their first semester of college. The film is 25 minutes in length. Ethan Hawke, who had known Bryan Singer as a child in New Jersey, agreed to star in it at the same time that he was filming Dad with Jack Lemmon. Ottman also edited the film.
