We're all mourning David Bowie, who suddenly died Sunday, two days after his 69th birthday as well as the release of his 25th album, "Blackstar." Among those grieving is Duncan Jones, his son. Jones, the son of he and Angie Bowie, grew up to become an accomplished filmmaker, having made "Moon" and the sharp "Source Code." He's also hard at work on "Warcraft," based on the video game series.
