Deliberate mistake: Throughout the film, scenes of several Cole Porter productions are shown being performed. These scenes all contain a well-known musical number. Two scenes in particular (after the Alanis Morissette number and immediately after the "So in Love" duet) end with the lead singer/singers bowing to the audience and then waving the other cast members on stage to take a company bow. The problem is that neither of those numbers appear at the end of the shows being "performed." The "So in Love" duet, for example, most definitely appears in the musical "Kiss Me, Kate" well before the Act Two finale. I assume that these mistakes were filmed deliberately to emphasize the importance of the songs in question, but they are still errors.

1 deliberate mistake
Directed by: Irwin Winkler
Starring: Kevin Kline, Ashley Judd, Jonathan Pryce, Kevin McNally
Factual error: When Cole Porter sits in on the "Kiss Me, Kate" rehearsal (when the cast is singing "Another Openin', Another Show"), he calls the soloist by name - Ms. Morison. This refers to the original leading lady, Patricia Morison. However, the main vocals for "Another Openin', Another Show" are sung by a completely different character than the one originated by Patricia Morison. In fact, Morison's character does not sing at all in that musical number.
Linda Porter: I had no idea how hot the climate would be, everything grows wild here and the pickings are far too easy.
