Harte has been married to English actress Julia McKenzie since 1971.
The Star Wars Insider 74 article Who's Who in Echo Base, written by Josh Radke, incorrectly states that Jerry Harte played Echo Base controller Romas Navander, a Star Wars Legends character, in The Empire Strikes Back. In fact, the Navander role was portrayed by actor Burnell Tucker, while Harte played another Echo Base officer who was not named in Star Wars Legends.
