Revealing mistake: In an early scene Cole and his future wife watch fireworks over Paris through a doorway overlooking a balcony. The explosions are reflected on the glass of the open door, which is at an angle to the POV. But the CGI fireworks and their reflection in the glass are squashed to fit into the foreshortened pane of glass. In reality the reflected image would be like any mirror, with the image inverted left-for-right.

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.
