Giorgio Moroder wrote most of the music for the songs on the soundtrack. Tom Whitlock, who wrote the majority of the lyrics to these songs, was actually the mechanic who worked on Moroder's sports car.
Riding on the back of this film's success, the US Navy set up recruiting booths in the major cinemas to try and catch some of the adrenaline charged guys leaving the screenings. They had the highest applications rate for years as a result.
When the guys, as students, were first being spoken to by Charlie in the hanger, Maverick explains that he gave "the bird" to a MiG. She asks how he saw the MiG up close, and he says he was flying inverted. Right then, Ice coughs "bullshit" and the guys laughed. The "bullshit" line was ad libbed by Val Kilmer.
The Navy only authorized two actual missile shots to be filmed for the movie. You can clearly pick out these two shots, ultimately shot from several angles each in order to use both shots repeatedly during the dogfighting scenes, because the aircraft firing the missile is holding a steady altitude and heading, something that would never happen in a real close-in dogfight. All other missile shots shown in the movie were conducted using miniatures of both the planes and rockets. The company that produced and fired the model missiles did such a good job that the Dept. of the Navy conducted a preliminary investigation into whether any additional live firings of missiles, beyond the two originally authorized, were done for the filmmakers.
Charlie's "older man" date at the officer's club is the real-life "Viper", Pete Pettigrew. He is a retired Navy pilot and TOPGUN instructor, and shot down a MiG during the Vietnam War. He served as the technical consultant on the film.
Michael Ironside stated in the DVD commentary that he was so convincing as an officer that when he heard someone running towards him below decks, he got on to the sailor who was running. The sailor saluted and slowed down until he got out of Ironside's line of sight and started running again. The sailor never knew that Ironside was an actor on the film.
After the "Car chase" when Charlie tells Maverick that she didn't want anyone to find out she was falling for him, Maverick originally had a line to say. Tom Cruise forgot the line and "ad libbed" by kissing Kelly McGillis instead. Tony Scott liked it so much, he left the scene like that.
When Maverick receives his orders to the carrier following the graduation ceremony, there is a pilot standing behind him, with a mustache and wearing sunglasses. The pilot is "Heater" C.J. Heatley, a real-life former F-14 air show demonstration pilot and TOPGUN instructor.
Rick Rossovich stated in the DVD commentary that he was kicked off of the ship used for filming because he smarted off to an officer. Rossovich had gone to sleep in the bunk (more commonly called a rack) he was assigned to, but didn't like being so close to the nuclear reactors that powered the ship, so he moved. When he smarted off to the officer who wanted his bunk back, Rossovich was told to report to the captain who ordered him thrown off the ship for disrespect.
Pete "Maverick" Mitchell's first name was Evan in early scripts of the film. It was later changed to Pete as an homage to Pete Pettigrew, who worked on the film (Pettigrew appears in the bar scene early in the film as Charlie's older male date.)
Paramount Pictures commissioned Grumman, the makers of the F-14, to develop and install special camera mounts on the plane. This allowed the filmmakers to use real aerial point-of-view footage of the Tomcat in flight.
Judas Priest were asked to contribute the song "Reckless" to the soundtrack, but declined because they thought the movie would flop. Two years later, they contributed a cover of Johnny Be Good (1988) to the movie of the same name, which turned out to be a flop.
The love scene between Tom Cruise and Kelly McGillis was filmed after initial test screenings. Moviegoers complained that there was no love scene, so the company obliged. McGillis, however, had already dyed her hair darker for her next film. This is why the scene is tinted blue. Also noticeable as a subsequent shoot due to the longer length of Tom Cruise's hair (particularly in front).
The character portrayed by Kelly McGillis is based on Christine Fox, a civilian flight instructor the producers met on a visit to Miramare while doing research to prepare for the movie. Ms. Fox is as of 12/5/13 the Acting Assistant Secretary of Defense, the highest post ever held by a woman at the Department of Defense.
Don Simpson was known for being a very hands-on producer but was noticeably absent during the making of Top Gun. This was mainly due to the fact that he was in rehab, being treated for his major dependency on prescription drugs. His use of illegal narcotics also led to him becoming increasingly paranoid, to the extent that he rarely left his home.
During the filming of some sequences from civilian aircraft, longtime Hollywood stunt pilot Art Scholl was killed. A biplane he was flying crashed off the Pacific Coast. The film is dedicated to his memory.
The piano scene and the final bar/jukebox scene were shot in a San Diego restaurant called Kansas City BBQ, at the corner of Kettner Blvd and W. Harbor Drive. The restaurant housed many props and memorabilia from the film, including the jukebox and Maverick's flight helmet sits behind the bar in a locked display case. However, on June 26, 2008 Kansas City BBQ suffered a grease fire that destroyed much of the interior of the establishment. The restaurant has since been repaired to its original state, but all of the original Top Gun (1986) memorabilia on display was lost.
During the pilot briefing before the final furball, Stinger mentions that the MiGs carry the Exocet anti-ship missile. This is a real missile, however, it is of French manufacture and has never been used by the Soviet Union, Russia, or any of the countries that made up the Soviet Union.
The pilot that gets "flipped off" by Maverick and Goose is Admiral Robert Willard, the lead flight choreographer for the film. He was Commander of the United States Pacific Fleet (2007-2009) before transferring to United States Pacific Command.
In several locker scenes, one of the lockers is labeled as belonging to "TEX". This is the call sign for one of the top gun instructors and Mig pilots that worked on the film, Lt. "Tex" William Spence.
An original draft of the script specified that the final showdown involved North Korean aircraft. The final script made the nationalities of the enemy planes unknown and simply specified they were MiGs over the Indian Ocean.
The scene where Maverick follows Charlie into the bathroom was filmed at the Headquarters Building at Recruit Training Command, San Diego. [The Naval Training Center installation was later demolished in the late 1990's to make way for more Navy housing. Before the headquarters building could be inspected for demolition, the bathroom counter that "Maverick" leans on and "stress tests" was stolen.]
The elevator scene (where Maverick and Charlie meet after Mav's workout) was filmed post-production. Kelly McGillis's hair had already been colored for another movie role, which is why she is wearing a hat. Tom Cruise's hair is longer in the shot as well.
While many terms used in the movie either match or are closely based on real terms used by naval aviators and the pilots in general, the term "going ballistic" is a real phrase that was wrongly used to describe a pilot successfully reaching maximum speed, when it actually meant that the pilot was going too slow to control of his aircraft, i.e., the aircraft is ballistic like a ball thrown in the air and will be influenced by gravity rather than the control surfaces as there is too little airflow over them. The phrase is used in Air Combat Maneuvers where the aircraft is put into a vertical or nearly-vertical climb and slows below an acceptable control speed. The pilot is then just along for the ride as gravity takes over and the airplane begins to descend and accelerate back to flying speed. The call is given over the radio to warn other pilots that the aircraft cannot maneuver to avoid a collision.
Other real names of the pilots/RIOs were that are not otherwise mentioned in the movie, but only by their callsigns are: Hollywood: Lt. Rick Neven; Wolfman: Lt(jg) Leonard Wolfe; Slider: Lt(jg) Ron Kerner; Cougar: Lt . Bill Cortell; Merlin: Lt(jg) Sam Wells.
The call sign 'Sundown' is a reference to VF-111, a squadron of F-14s called The Sundowners that have the same sundown graphic on their tail fins as on Sundown's helmet. VF-111 supplied the F-14s used for Maverick & Goose and Iceman & Hollywood's Tomcats. In some shots 'VF-111' is visible on the under-engine fins of the F-14s.
The callsign 'Ghostrider' that Maverick uses for his plane was the name of a real F-14 squadron (VF-142), and a model of a Tomcat from that squadron can be seen behind Sundown in the shot where Maverick tells Slider he stinks.
Two video games based very loosely on the movie were released on the Nintendo NES. While the first game really had no storyline, the second actually served as a "sequel" storyline, regarding Maverick going up against a new group of villains.
The trivia items below may give away important plot points.
A script for "Top Gun 2" was completed shortly after the release of the film, but it broke down in pre-production because 1) the military's technology had become updated and they didn't want camera crew anywhere near their new aircraft and 2) Tom Cruise did not want a sequel and finally agreed to star in one for a very high amount that was deemed "unaffordable." The script followed the further adventures of Maverick as an instructor at the Top Gun academy, the twist being a cocky female reminiscent of himself joining the team.
Goose's real name is Nick Bradshaw. His name is briefly seen on a flight patch on top of his dresser when Maverick goes to retrieve Goose's belongings after he dies. It can also be seen numerous times written on the side of the F-14 he and Maverick fly. It is most noticeable when Goose hits the canopy after ejecting.
The film was originally going to have a scene near the end where Maverick visited Goose's grave. A filmed version of this scene was never released, however still screen shots from what such a scene would have looked like are available on the special edition DVD.
