Sullivan's Crossing : Scott Patterson as "Sully" Sullivan Jessie Redmond/Fremantle EXCLUSIVE: Sullivan's Crossing fans are in for a shock when they tune in for the upcoming fourth season of the popular Canadian series - one of its three main stars, Scott Patterson, will not be in it. That explains why the Gilmore Girls alum was not in the recently released key art, trailer and credits for Season 4 of the romantic drama, which debuts on the CW on April 20 and will subsequently be headed to Netflix in the U.S. where the series' first three seasons have done very well.
