Trivia: In the opening musical sequence when they jump out of the pool, the lady behind Austin can be seen laughing because her swim hat has fallen down.
Trivia: The English version of the theme song is not a remixed version, as the previous four movie themes were - this theme has the same music and tempo as the TV version. The composers did not create a second verse to the song "Master Quest," so it has the same lyrics as the TV version all the way through.
Trivia: Early in the movie, when George is speaking to John, he says, "Me Tarzan, you Jane." Even though this line has been synonymous with the character Tarzan, it has actually never been said by Tarzan at all in any movie or any stories written about Tarzan's adventures. This is officially the first time the line is used.
Trivia: The secret project created to use the Hermes to return to Mars to rescue Watney was called Project Elrond, a reference from the Lord of the Rings (also used in the original book of The Martian). Mitch Henderson, played by Sean Bean, was an attendee at the Project Elrond meeting. Sean Bean also played Boromir, who was an attendee at the Council of Elrond in the LOTR movie.
Trivia: When Keith Richards is looking up the rule in the pirate code book, the skull ring on his finger is not a prop; he has worn it since receiving it for his birthday in 1978 from a famous London goldsmith, who used a real skull when modelling the design.
Trivia: The sound of Vigo growling is exactly the same growl that the terror dogs from the first Ghostbusters make.
Trivia: In the entire film, there are only two "homegrown", real humans - Tank and Dozer. They both have names of machines.
Trivia: The two old men near the end, talking about it being "old school" are voiced by Frank Thomas and Ollie Johnston, two Walt Disney animators who worked on such classics as Bambi and Cinderella.
Trivia: John Rhys-Davies is missing the end of his middle finger on his left hand due to a farming accident as a child. The make-up artists made artificial, gelatin fingertips for him to wear in the movies. Davies one day, cut the tip in half, put 'blood' in it and closed it up. He went over to Peter Jackson (unaware of the gelatin tip) and said, "Boss, I've had an accident, look what happened". Jackson saw a small cut, but Davies bent the tip back and it split open, gushing.
Trivia: George Clooney (Everett) was going to sing "Man of Constant Sorrow" for the film but his singing voice was very poor so he ended up lip-synching the songs instead. He said "I'm not my aunt [referring to the late singer/actress Rosemary Clooney, best known for her role in "A White Christmas" (1954)]. I decided it would be easier to just do a passionate lip-sync." He was so nervous that the tapes of his singing would get out that he returned to the studio to ensure all the evidence had been erased. The musical director of the film confirmed this but said "George is a very good singer but that style of music is very difficult and one almost has to grow up singing it in order to sing it convincingly. George did a really good version of the tune but it wasn't as good as he wanted."
Trivia: Kevin Smith once happened upon a demonstration against this movie by a group of Catholics. Since nobody recognized him, he simply joined in.
Trivia: In the scene after Hiccup finally gets Toothless' new tail fin to work, and the two are relaxing after they fly through the fire ball, the two are greeted by a group of tiny dragons. This little dragon was actually what Toothless was originally going to be, as he was in the book, until they changed him to a dragon big enough for Hiccup to ride to suit the movie. (00:46:15)
Trivia: The knife that is given to Louis by the pirates is the exact same knife that Buck had in the previous film.
Trivia: In the film, Bond says to M, "So you want me to be half-monk, half-hitman." This is a reference to the character John Ballard (played by Daniel Craig) in the 1998 film "Elizabeth".
Suggested correction: Johnny Weissmuller said it in his Tarzan movies.
This is actually a popular misconception. Johnny Weissmuller never actually said it in any of his Tarzan movies. He said it during an interview where he was describing the character. But he never actually said it onscreen during any of the movies. So the trivia is 100% correct.
