Korngold-the themes from Juarez and the prince and the pauper ending up in his violin concerto
Korngold used more themes than that. See his other symphonies and hear material from 'Captain Blood' and 'Elizabeth and Essex', and of course 'Sursum Corda' and Robin Hood.
Only a matter of time before someone mentions Miklos Rozsa violin concerto and the 'Private Life of Sherlock Holmes'.
Jerome Moross and his chamber music.
It shouldn't matter really. As long as it's their own material.
Corigliano- altered states ends up in his first symphony
There's a bit of his clarinet concerto in Altered States, and a bit of Altered States in the Pied Piper Fantasy, but I hear nothing of that score in the First Symphony. The symphony does however make use of the entire battle cue from Revolution.
Plagiarism is passing off the work of someone else as one's own.
Using your own music -- music that you wrote and that you OWN authorship of -- is yours to do with as you please.
Getting all het up over Korngold using his film themes in his concert works is inconsequential histrionics.
Get over it.
EXACTLY.
And often the material from movie scores is expanded upon and re-worked for concert pieces in a way that allows creativity and development that can't be done in scores because of the timing to picture issues.
Even though no one cares about this thread, it was fun-ish (?) to hear some of Goldenthal's Batman Forever in his Vietnam Oratorio, Fire Water Paper (released after Batman, written beforehand).
