UNDATED (AP) — The writer and director of the movie “Guardians of the Galaxy” had wanted David Bowie to do a cameo in the sequel, and Bowie was open to the idea. James Gunn writes on Facebook he heard from mutual friends that Bowie wasn’t doing well, then heard back Bowie was OK and the cameo could potentially happen. Bowie’s song “Moonage Daydream” was on the best-selling soundtrack of the first movie, and Gunn says he’s trying to work another Bowie song into the sequel. He says it seems appropriate for Bowie to be the only artist with songs on both soundtracks.
