Brad Wright:(On which SG-1 episode was the most intense to shoot) That depends on what you call intense. For The Nox, it rained so hard we were actually rained out of our location. I remember being on the phone with Michael Greenburg, looking out my office window, and telling him to get the crew to shelter because I could see the lightning hits on the mountains. For me that was intense. For sheer difficulty of production, I could include our season two opener, The Serpent's Lair, as well as There But For the Grace of God and Solitudes, where we actually built a glacier crevasse, and refrigerated the studio. Poor Rick and Amanda were really freezing onscreen.
