In recent interview with YRB Magazine, Erin Davis (Miles’ son) and Vince Wilburn Jr. (Miles’ nephew) noted that a new writer, Steven Baigelman, is collaborating with Don Cheadle on an updated draft of the Miles Davis‘ movie script. But in the very same interview, Wilburn Jr. also points out that Herbie Hancock is planning to score the movie.
Here are some quotes from the Interview:

YRB: Now that the box set is out, how do you plan on taking his legacy further?

Erin: There’s a lot of different things in the works. We can talk about it when there’s more stuff, but Vince is also producing a movie of his life.
Vince: Yeah, Herbie Hancock’s going to score it and Don Cheadle’s directing and starring.

YRB: Yeah, tell me about that. How far along are you?
Vince: We’re in the process of OK’ing the script with a new writer. Don didn’t like the other writer that was attached to the movie, so there’s a new writer named Steven Vegelman that Don’s writing with. Once is the script is OK’d by the family, then we go into production. Erin and I are putting together some live concerts and he recorded everything, more tapes from the soundboard. And there’s a vast amount of music in the vaults, so we’ll get back to you when we get some projects together. We’ve got another thing coming out on Warner/Rhino, he left Sony and signed with Warner. I think it’s called The Warner Years or the Rubberband Sessions, he had a song called “Rubberband.” But we’ll hit you back when we know when it’s coming out.
