* CutSong:
** "Too Much For One Heart", sung by Kim. Lea Salonga still keeps it in her concert repertoire and with good reason. There is also the finale "The Sacred Bird", heard initially when the show opened in London, but since pared down.
** Ellen's solo, "Her or Me", heard on the London Cast Recording, is modified into "Now That I've Seen Her" in all others, basically by replacing the first line with the second.
** Inverted in the London revival, as Ellen has been given a new song, "Maybe", intended to generate more sympathy for her, an often reviled character.
* FakeNationality: The Filipino Lea Salonga played the Vietnamese Kim.
** In predominantly white countries such as Hungary or Norway, Kim has been played by a WHITE actress wearing a black wig.
** FakeMixedRace: This also goes for Jonathan Pryce. At first, the Actor's Equity Association refused to let Pryce reprise his role of the Engineer in the Broadway production, because Pryce is a Caucasian playing an Asian role and would offend the Asian community. However, it was counter-argued that the Engineer is Eurasian (half-Vietnamese and half-French), and that Pryce was being discriminated because he is Caucasian. After pressure from Cameron Mackintosh (who also threatened to pull the show from Broadway), the general public, and other members, the Equity Association finally agreed to let Pryce be in the show.

** FakeAmerican: Basically everyone playing an American in any of the non-US productions.
* StarMakingRole: This is what catapulted a then 17-year-old Lea Salonga into Broadway stardom. She would return to the role off and on for more than fifteen years.
* StuntCasting[=/=]BookEnds: The show began and ended its Broadway run with Lea Salonga in the title role.
