Christopher Reeve, who played the dual role of Clark Kent and Superman in four theatrical features of the 1970s and '80s, makes a guest appearance in Smallville as Dr. Virgil Swann. Having dedicated his life to studying all things extraterrestrial, the wheelchair-bound Swann is fascinated by a newspaper story regarding Clark Kent (Tom Welling). Using the fragmentary evidence at hand, Swann concludes that young Clark is "not of this world" -- and, as a bonus, both Swann and Clark have simultaneously received a cryptic message in an unknown language, a message that will have a major impact on Clark's future on Earth.
