- Bud being a sci-fi nut; he gives the occasional reference to Star Trek and Quantum Leap, even naming one of his kids after James T. Kirk. Donald P. Bellisario even cameos as himself at a sci-fi convention, and his star on the Hollywood Walk of Fame is featured in one episode. The Star Trek connection is interesting considering it has the same copyright holder as JAG (i.e. CBS / Paramount.) Cross-promotion anyone?
Captain Boone: Chief, if I bagged a Klingon, I believe you'd know what Flag to paint on her.Chief Ned Bannon: Klingons are Easy, now a Romulan Warship now that might be a problem, they're invisible.
- The name of the fictional aircraft carrier USS Seahawk, first seen in the pilot, is probably an homage to that Errol Flynn movie.
- It is also interesting the first Scifi reference in the show - in the pilot, when Captain Boone (the CAG) and Lieutenant Arrutti return from a flight after having shot down a hostile aircraft, as Boone is about to get out of the cockpit, one of the yellow-shirt flight deck crew starts to paint on the F-14.
- So there's Trek fans among the fictional Seahawk crew aside from Bud, so an implied subversion of Hollywood Nerd.
- Star Trek fans who don't know that Klingons also have cloaking devices.
- In "Pilot Error", Harm compares the situation to the movie Fate is the Hunter, explaining to Meg (who hasn't seen it) how they found out the cause of a plane crash by recreating all of the minute details of the flight.

They had a woman a lot like you: Claire Trevor.Corporal John Edner: Yep, prostitute Duke fell for.Lieutenant JG Meg Austin: You're comparing me to a prostitute?Corporal John Edner: No, ma'am. I didn't say that.Lieuteant Harmon Rabb: I did, and I meant she was spunky like you.
- In "Boot", an episode centering on an investigation into the death of a Marine recruit at Boot Camp, the two Drill Sergeant Nasties spend some idle time watching The D.I., an old Jack Webb film about Marine Boot Camp. This also serves as some clever foreshadowing if you're familiar with the film's history, being made in response to a highly-publicized incident where several Marine recruits drowned while marching through a swamp at night. The episode's climax has the killer and Meg Austin both nearly drown in the swamp during a nighttime foot chase.
- In Season 2s "Washington Holiday" (itself a take on Roman Holiday) when the Romanian Princess has escaped from doing her duties and went to a night club instead: Harm, as her military escort dressed in whites, carries her back to the limousine causing a woman in the background to say: "This is so like An Officer and a Gentleman".

Athos, Porthos, Aramis and D'Artagnan.
- Mac questions an enlisted marine about their captains unorthodox training methods in "Force Recon". Considering that the captain has the nickname Duke like John Wayne, she comments that there seems to be case for movies.Sergeant Tesla: Captain Koonan is the finest officer I've ever served under, ma'am. I'd follow him to hell and back.Mac: It seems to be a case for movies.Sergeant Tesla: Ma'am?
