  The distinct models that describe spin 1 and 2 massive excitations in 2+1
dimensions are analized, showing their equivalence (between models of same
spin) and analogies (between models of different spin). Topics as spontaneous
symmetry breaking and anyonic behaviour, in these models, are analized. A
massive gravity model is introduced. This model is diffeomophism invariant, but
it is not Lorentz invariant.
