Just suppose that you’re young and gifted; hey, you’re a freaking musical prodigy. Not only that, you are extremely beautiful. You play the harpsichord like an demon, fiddle with the best of them, sing angelically, and “hear notes in your head” even though you’re not quite sure how to “write them down.”
You’re well on your way to being a musical goddess, only, your bratty 
little brother, whom your father flagrantly favors, gets all the attention. He’s none other than Mozart.
He’s not a Mozart. He’s the Mozart!
You know, Wolfie. Amadeus!
I very much enjoyed the French costume drama, “Mozart’s Sister,” also an 18th century feminist sob story … playing at one of my favorite old-school New York art houses, the Cinema Village. Enjoy!
Review round-up on “Mozart’s Sister” here.
My daughter did a production of “The Magic Flute” with her Children’s Theater in a small Georgia town south of Atlanta. She kept Mozart’s music, changed the action to a show that Wolfie and Nannerl put on “right here, in our own back yard!” a la Mickey Rooney and Judy Garland. Great success! One local critic wrote: “this is the first time I really understood what goes on in The Magic Flute – which shows one must not dilute art when bringing masterpieces to the uninitiated, just meet your audience on a level where they can follow the action. (To fans, if you like this movie, do go read Wolfie’s diaries they are full of jokes, innuendos, burps, farts, and fun.)
LOVE your description, and can’t wait to see this film!
Agreed: very good movie.
