Richard Garland's last acting credit before his early death at the age of 41, just three months after his "Mission: Impossible" role. Due to alcoholism and related medical issues, he appears far older.
First series appearances for Lloyd Bochner (Major Zelinko) and Larry Linville. Each actor will appear in two more episodes. Linville was at this time enjoying a recurring role on another Paramount-produced series, Mannix (1967), and in 1972 landed his best-known role playing Major Frank Burns on M*A*S*H (1972).
