The Bridge at Kang So Ri - S5-E18
Trivia: When Harm is landing the 747, there is a camera shot of Air Force One. (The Presidential seal which is located near the forward doors is briefly visible) There is also a scene immediately afterwards of vehicles following the plane on the runway. These two scenes are from the Harrison Ford movie, Air Force One.
Trivia: The new neighbor moving into Harm's apartment building is played by Nanci Chambers, who is married to David James Elliott, who portrays Harm. Chambers later had a larger supporting role as Lt. Loren Singer, an ambitious lawyer in the JAG office.
Trivia: Beginning in season 8, Dean Stockwell appeared as Senator (and later, SECNAV) Edward Sheffield. This was the character he played on First Monday, another Donald Bellisario series.
Trivia: In addition to his regular role as Harm, David James Elliott also played Harm's father in flashbacks scattered throughout the show.
Trivia: David James Elliott, Catherine Bell, and Patrick Labyorteaux were the only actors to appear in all ten seasons. Except for a few special episodes, Elliott and Labyorteaux were the only ones to play the same character, while Elliott was the only actor to appear in every episode.
Trivia: Donald Bellisario makes an uncredited cameo as himself arriving at the Quantum Leap convention.
Trivia: Steven Culp cites the scene in which Webb gets decked by Admiral Chegwidden as the most memorable event of his career.
Trivia: Donald Bellisario was originally against casting Catherine Bell as Mac. Since Bell had played a murder victim in the last episode of season 1, Bellisario felt her re-appearance as Harm's new partner in the first episode of season 2 would confuse the audience. Bell eventually won Bellisario over, and she remained on the show for the rest of the show's run.

Trivia: Although Mark Harmon (who appeared in season 8) became the focal point of the spinoff, John Ashton was the first actor to play an NCIS agent on the show.
