Here we review recent theoretical studies of electron correlations in these compounds. In particular, we discuss models of electron-vibron interactions, electron-electron interactions, and intermolecular hopping. We show that the origin of novel electronic phases lies in {\em local} degeneracies of C60; a direct consequence of the high molecular symmetry.Latex, to appear in Fullerene Science and TechnologyStrongly Correlated Electronstext
