I'd have to go with Bergman's film of THE MAGIC FLUTE, followed by Zeffirelli's LA TRAVIATA. The TRAVIATA kind of comes to a halt in the second act, and Domingo is just way too old, but it works anyway.
The overture section to Bergman's MAGIC FLUTE is one of the best things he ever did. Enchanting all around.
