What do the movies "Once Upon a Time in the West", "La cage aux folles", "The Untouchables", and "The Hateful Eight" have in common?

They all have musical scores composed by Ennio Morricone.

Morricone is best known for his "spaghetti western" compositions in early times and perhaps for his work with Quentin Tarantino in later times, but has written the scores for hundreds of movies and in many genres, as well as writing concert music and symphonies.

He received an honorary Oscar in 2003.
