  We carry out an analysis of the pentaquark $\Theta^+$ photoproduction with
polarized photon beams. Kinematical and dynamical aspects are examined for the
purpose of determining $\Theta^+$'s spin and parity. It shows that the
polarized photon beam asymmetry in association with certain dynamical
properties of the production mechanism would provide further information on its
quantum numbers. Facilities at SPring-8, JLab, ELSA, and ESRF will have access
to them.
