I am shocked to note that no one (I read all 13 pages, I checked!) has mentioned the newest rendition of Around the World in 80 Days (2004).
Its original in 1958 was somewhat less period with the garb, I believe, but still quite charming.
Honorable mention, the film presentation of Phantom of the Opera (the phantom himself was extremely inventive).
I'd also like to note (as a far-too-adult fan of Disney) that Beauty and the Beast is fairly steampunk (at least, her father is). In some ways, Kiki's Delivery Service is as well.
