Lucas has never had a studio affiliation, really--he's been all over the map, but people just associate LFL with Fox because of Star Wars, but its really incidental. THX was with Warners and Lucas hated Warners, Graffiti was with Universal and he hated Universal even more, Star Wars was with Fox and he hated Fox (and stuck it to them for every sequel), and Indy was with Paramount. Of course he's produced a dozen more films for even more studios. I think the only one he's never been with is MGM, but I could be wrong. This is the first Star Wars film without Fox, but thats misleading because it was never intended for theatrical release anyway, and none of the four Star Wars animated series (Droids, Ewoks, Clone Wars and Clone Wars) have been with Fox anyway.
