Superman joins SMALLVILLE August 2, 2007 News, Smallville Dean Cain (Superman in “Lois & Clark: The New Adventures of Superman”) will guest star in SMALLVILLE‘s seventh season as Dr. Curtis Knox, a villainous killer. Dean Cain will appear in the fourth episode of the season. Oh sweet memories… I was such a big fan of Lois & Clark: The New Adventures of Superman. I used to watch it every week with my mom. It seems like such a long time ago. At least it will be a blast from the past to watch Dean Cain in Smallville. The seventh season of Smallville starts on September 27th, and I cannot wait to find out if Lana will be back.
