For a probability measure with compact and non-polar support in the complex plane we relate dynamical properties of the associated sequence of orthogonal polynomials fPng to properties of the support. More precisely we relate the Julia set of Pn to the outer boundary of the support, the lled Julia set to the polynomial convex hull K of the support, and the Green's function associated with Pn to the Green's function for the complement of K.
