Top Secret!, the film:
- Awesome Music: for a movie that spoofs musical comedies of The '60s, they did a damn good job mimicking The Beach Boys and Elvis Presley.
- In-universe, as Nick Rivers' songs "Skeet Surfin" "Skeet U.S.A." and "Skeet City" hit the top three spots on Billboard's charts the same week. With the Nick Rivers / Tammy Wynette duet "Your Skeetin' Heart" rounding out the fourth spot.
- Nick's cover of Are You Lonesome Tonight.
- Ear Worm: "How Silly Can You Get?"
- Genius Bonus:
- "Sunday? That's Simchas Torah!"
- Shortly before an execution Nick is visited by a priest. He seems to read a prayer in Latin, but it's actually a mishmash of Latin phrases, like "Omnia Gallia in tres partes divisa est" — the (misquoted) opening line from Julius Caesar's Commentaries on the Gallic War common in school textbooks, or "veni vidi vici".
- The reverse-filmed sequence with Peter Cushing as the Swedish bookseller is based on the linguistic theory that to people who don't speak the language English sounds like Swedish when played backwards (and vice versa). If you watch the scene played forward it's clear the actors are actually speaking English.
- Harsher in Hindsight: The Nick Rivers marquee at the beginning listing "Time permitting: Frank Sinatra". The Grammys 10 years afterward had the same idea, cutting into Ol' Blue Eyes's Lifetime Achievement Award acceptance speech for a commercial break. (Granted, he didn't precisely have a speech prepared and only went on as long as he did due to being overwhelmed by the ovation when he walked out, and it ended on a good note, but for those watching it was still jarring.)
- Hilarious in Hindsight:
- The actor playing Déjà Vu shares the same name with the man whose presidency Hillary's uncle escaped from.
- Val Kilmer and Michael Gough work together for the first time. More than a decade later they would be Batman and Alfred respectively in Batman Forever.
- In the song, How Silly Can You Get?, Val Kilmer sings about a night in Paris, described as "gay Parie." In Kiss Kiss Bang Bang, he plays a character named Gay Perry.
- Hillary's name meaning: "It means 'she whose bosoms defy gravity'." So here's Hillary Clinton about 36 years later...
- Billy J. Mitchell (Martin, Nick's agent) plays a character who dies with a big smile on his face. 11 years later, he'd play another one who does the same thing.
Top Secret!, the magazine:
- Narm: The early issues can read like this between the rather clumsy writing, articles resembling impromptu fanfiction rather than actual gameplay descriptions, and some authors elevating computer games to the level of mystic lore.
