Other mistake: On the first day at Stuart's apartment Leopold wears some green 19th century trousers he wasn't wearing during his time travel, and which surely weren't part of Stuart's wardrobe. (00:30:05)
Kate & Leopold (2001)
1 other mistake - chronological order
Directed by: James Mangold
Starring: Hugh Jackman, Liev Schreiber, Meg Ryan, Breckin Meyer, Natasha Lyonne
Factual error: In the begining at the bridge ceremony, the band plays Manhattan Beach by John Philip Sousa. However, Manhattan Beach was composed in 1893. (00:00:50)
Leopold: If it is a ransom you seek, my uncle won't pay a cent. Except, perhaps, for my demise.
Trivia: In the scene where Leopold is writing a letter to Kate inviting her to dinner on the roof, he's writing with the quill in his right hand. Hugh Jackman is left handed.
