As an in-joke, Rothbart, voiced by Jack Palance, does a one-armed push-up during the song "No More Mr. Nice Guy," just as Palance famously did during his acceptance speech for at the Academy Awards, when he won Best Supporting Actor for his role in City Slickers (1991).
In the beginning of Rothbart's song, "No More Mr. Nice Guy," Rothbart causes an earthquake in the floor by shooting magic at it. In the flash of magic, the number "6.8" can be seen. This could be a reference to the earthquake being rated a 6.8 on the Richter scale.
This film was one of the biggest animated box office disasters in history, barely grossing over $9 million domestically and worldwide - less than half of its budget. One of the main reasons for this was competition since the animated movie was released at the same time as some of the biggest box office juggernauts of its time. Some of the hits the Swan Princess had to compete against at the box office were Star Trek: Generations (1994), Interview with the Vampire: The Vampire Chronicles (1994), The Santa Clause (1994), Léon: The Professional (1994), _Stargate_, Pulp Fiction (1994), Miracle on 34th Street (1994), and the re-release of The Lion King (1994). On the other hand, the animated movie was popular enough on VHS and DVD to get six more straight-to-VHS/DVD sequels with additional sequels being planned.
Derek's last solo voiceover thought in the song "This is My Idea," "[Odette] started out as such an ugly duckling, who somehow suddenly became a swan," foreshadows the transformation placed on Odette by Rothbart.
The court composer who works for Prince Derek's royal family is called Lord Rogers. This could be a reference to composer Richard Rodgers of Rodgers and Hammerstein fame. The pair was one of the most successful and influential writing teams in the history of American musical theater. Composer Richard Rodgers (1902-1979) and lyricist-dramatist Oscar Hammerstein II (1895-1960) created such classic Broadway musicals in the 1940s and 1950s as Oklahoma!, Carousel, South Pacific, The King and I and The Sound of Music, all of them later turned into hit movies - Oklahoma! (1955), _Carousel_, South Pacific (1958), The King and I (1956) and The Sound of Music (1965)..
The trivia items below may give away important plot points.
Rothbart disguises the Hag as Odette wearing a black dress to fool Derek into making the vow of everlasting love to her, as opposed to Odette. This pays tribute to the classic ballet that inspired the movie, except Rothbart disguises his daughter, Odile, to resemble Odette (and is usually danced by the same ballerina who plays Odette). The difference is that she wears black, as opposed to Odette's white garments.
The Swan Lake's story that the movie is based on has at least five general variations when it comes to its ending. Some are happy but most are more or less tragic. The prince defeats the wizard and saves the Swan Princess, the prince is defeated and the wizard gets the Swan Princess, the prince and the wizard kill each other, the prince accidentally kills the Swan Princess or the prince and the Swan Princess choose to die together to escape the wizard's curse. This final alternate ending usually has one of two outcomes - their self-sacrifice proves their undying love for each other which breaks the spell and they transcend to Heaven or the prince also becomes a swan and the two lovers fly away together.
