His brother, Miles Copeland III was the founder of I.R.S records and managed The Police, as well as Stewart's interests in other music projects. His other brother, Ian Copeland (RIP) was a pioneering booking agent who represented the Police. His father, Miles Copeland, Jr., was a founding member of the Office of Strategic Services (OSS) and the CIA, according to his 1989 biography and files released by the CIA in 2008 [here](https://www.theguardian.com/world/2008/aug/14/usa
Stewart Copeland actually worked on a shit ton of movie soundtracks, working on movies like Wall Street (1987), Surviving the Game and Fresh (1994), Good Burger (1997), She's all that (1999)... He worked on TV Soundtracks on things like The Equalizer (1985) and Dead Like Me (2003), and as far as the video game soundtracks, he actually worked on ALL the Spyros 1-4 as well as Alone in the Dark: The New Nightmare (2001).
As far as his studio work, he worked on classic albums like Airborne's Curved Air (1976) where he wrote the tracks "Heaven" and "Desiree" after he realized you got paid more as a songwriter, all his marvelous work with The Police, as well as his work with Oysterhead's The Grand Pecking Order (2001).
And for anyone interested in Stewart's influences, he grew up listening to a combination of Lebanese music, rock and roll, jazz, and obviously tons of reggae, picking elements of those genres as the song or the need dictated, and he has cited Mitch Mitchell (Jimi Hendrix Experience) and Ginger Baker (Cream, Blind Faith, Ginger Baker's Air Force). While we're talking about Ginger I'd like to recommend "Beware of Mr. Baker" a documentary about his life if you want to know more about this other legendary drummer.
