  We use the feature that the gravitational Compton scattering amplitude
factorizes in terms of Abelian QED amplitudes to evaluate various gravitational
Compton processes. We examine both the QED and gravitational Compton scattering
from a massive spin-1 system by the use of helicity amplitude methods. In the
case of gravitational Compton scattering we show how the massless limit can be
used to evaluate the cross section for graviton-photon scattering and discuss
the difference between photon interactions and the zero mass spin-1 limit. We
show that the forward scattering cross section for graviton photoproduction has
a very peculiar behavior, differing from the standard Thomson and Rutherford
cross sections for a Coulomb-like potential.
