  High temperature superconductivity in doped Mott insulators such as the
cuprates contradicts the conventional wisdom that electron repulsion is
detrimental to superconductivity. Because doped fullerene conductors are also
strongly correlated, the recent discovery of high-critical-temperature,
presumably s-wave, superconductivity in C$_{60}$ field effect devices is even
more puzzling. We examine a dynamical-mean-field solution of a model for
electron doped fullerenes which shows how strong correlations can indeed
enhance superconductivity close to the Mott transition. We argue that the
mechanism responsible for this enhancement could be common to a wider class of
strongly correlated models, including those for cuprate superconductors.
