Don Cheadle Learned Trumpet for Miles Davis Movie

Don Cheadle wrote, directed and starred in "Miles Ahead," a non-traditional biopic about jazz legend Miles Davis.

He said the whole project was a real labor of love. That's why he decided to actually learn how to play the trumpet, just as Davis did. "It was important to me to learn how to play because at some point in my development, Miles was as bad as I am now," he laughed. "Maybe he was 8 or 9 years old."
