Ellery Queen: Don't Look Behind You

Ellery Queen: Don't Look Behind You is a 1971

The film was intended to spawn a new television series like the earlier versions of the character (The Adventures of Ellery Queen).^[2] Richard Levinson and William Link authored the script but were so dismayed with the changes made during production that they took their names off and instead used a pseudonym, "Ted Leighton".^[2] This is the only Ellery Queen story or film in which Inspector Richard Queen is portrayed as Ellery's uncle instead of as his father. Critics speculated that this change was made because Harry Morgan was only eight years older than Peter Lawford and because the two had different accents (American and British).
