"The day comics grew up" [1989]

This was a British documentary about comic books, the writers and artists, from 1988 or '89, that was shown on the Australian ABC network back in mid-1990.
It looks at British and American comics, along with Japanese Manga, and touches on the then relatively new subject of [now very and primitive dated] video games. it also looks at the convention scene.
It has nice interviews with some of the creators [some of whom have since passed away], such as Archie Goodwin, Alan Moore, Jim Baikie, John Byrne, Tom Veitch, Cam Kennedy, and others.
