Answer:
Many of the orchestral scores for movies from the 1930s and 1940s were written by European composers.
Step-by-step explanation:
The movies in 1930s and 1940s had special inclination towards music. The artists that ran away from Europe and particularly from France to save themselves from persecution reached the United States.
They got opportunities to showcase their talents in United States and eventually grew to become big non-American composers in the American film industry.
The famous movies of this era are King Kong and Gone with the Wind.
