*The underwater scenes in "Descent" were inspired by a conversation in the hallway between Paul Mullie and me, early in season six. He was telling me about an idea he had for crashing a Goa'uld mothership into the ocean and filling it with water, but at the same time he feared that we could never actually do that. I said, "sure we can!" Special effects expert Wray Douglas duplicated a section of our stage set on a platform that could be raised and lowered in an enormous tank at the University of B.C. While watching dailies the following afternoon, each of us tried to hold our breath as long as Corin Nemec managed while shooting his underwater scenes. None of us managed to do it.
