This movie was based on the "Real Red violin" that was purchased in 1990 at Christies auction for 1.7 million dollars.
It was given to a young (now famous violinist) for her 16th birthday.

The ideal finish for a guitar top is actually NO finish at all (One of the Beatles had a guitar that was stripped of finish on the top and was said to have loved the results. Can't recall WHICH Beatle right off hand
FWIW-
You can't use blood for red color, no matter what preservative you add to the varnish. (many have tried.)
Being organic, it turns brown very quickly.
Also, it's a humorous anecdote, but it's well known in the violin world that one should typically stay far, far away from reddish violins. This is because the dark red color is almost always used to hide lousy grain. One COULD make a fine red violin, but why would you want to? That red Strad is one of very, very few good ones ever created, and by coincidence, it's not really one of the better sounding Strads in existence. It's actually fairly thin & strident sounding, as Strads go.
Oh, and the best finish for a guitar isn't really "nothing" as many musicians think.
You want a minimal finish, so as not to dampen the vibrations too much, but you must also control moisture in & out of the wood. Moisture kills vibrations very quickly, plus in really bad humidity the wood could warp, or split later if it gets too dry.
A really good finish can even enhance the high frequencies.
Lennon & Harrison had cheap guitars with heavy, plastic-y finishes, so those sounded better when stripped. A pre-war Martin would not.
