There is sadly not a lot of information out there for the early years of cinematics. Your best bet is old issues of "3dArtist" or "Cinefex". They float around on various torrent trackers. Blizzard has hardcovers for most of their franchises with a lot of history and there is also a behind the scenes & cinematics DVD Set for diablo. Square had behind the scenes books for all of the final fantasies prior to 13. There is also a TV documentary "Light&Magic" on Disney about ILM (LucasArts) which is primarily about their feature film vfx work but goes also into some details of "LucasArts" cinematics (mainly early Star Wars Games).

Interactivity Magazine would be another to check out. There's a few issues on Internet Archive.
