"Young Sherlock Holmes" (1985) should really be listed, I think about the first film where a CG character interacted in the "real" world instead of pure CGI scenes like "The Last Starfighter" or humans being bluescreened in like "Tron". I also second the "Dragonheart" nod as easily beating out Jar-Jar for full length (and non-annoying) CG character. If you ever do a television one, I have two nominations off the top. "Captain Power and the Soldiers of the Future" (1987) had regular CG characters and vehicles. Mainframe's "ReBoot" (1994) was the first fully CG series (and no one has yet beaten its third season in terms of entertainment).
