In "The Fugitive", he plays a Chicago police officer who is killed by the one-armed man, Frederick Sykes (Andreas Katsulas) while he is fighting Dr. Richard Kimble (Harrison Ford), prompting Chicago Police Department detectives to hunt Ford's character. This role was used in a subplot of the "Scrubs" episode "My Friend the Doctor" when J.D. (Zach Braff) notices Flynn's character in the film and believes that Flynn's Janitor character is the actor in the film. In 2008, he worked with Harrison Ford again, playing a suspicious law enforcement official as FBI agent Smith in "Indiana Jones and the Kingdom of the Crystal Skull".
