Zauberflöte), K 620 - Composed - 1791 is one of the more popular works in its genre. It has been updated and revised by several composers, and has even been filmed. The opening overture and other parts have been featured in films, including Miloš Forman's Amadeus.
Here's one of the more interesting performances of the Opera's overture in a new setting from British film Director Kenneth Branagh. This is a version in English set in a fictional World War I era and country. The choreography and cinematography are spectacular in the opening. I found the remainder of the film a little tedious, perhaps because it's difficult to adapt an opera to film. I think I'd rather watch it on stage, but I did appreciate this wonderful opening.

The music was conducted by James Conlon (I can't find information on the Orchestra - possibly the Los Angeles Opera Orchestra, for which he is the current conductor).
The film is not available on DVD in the US, unfortunately.
