Autumn in New York (2000)

Continuity mistake: When Charlotte leaves Will's apartment in the white gown he has given her, she is wearing a pair of white high heels. Later, at the party, they're dancing and she is wearing white platform sandals. The next morning, when she wakes up in his apartment and her clothing is strewn all over the floor, the original shoes are seen again.

Will: You think I'm too old for you?
Charlotte: Oh, no... I collect antiques, or I aspire to.
Will: Ouch.
