Christopher Reeve is coming back to the world of Superman, to lend some guidance to a young Clark Kent in an upcoming episode of the WB series "Smallville" to air during February sweeps, Reuters reports.
Network spokesman Paul McGuire tells the news service that Reeve, 50, will guest star as a brilliant scientist who provides Clark (actor Tom Welling) with "revelatory insight into his superhero destiny. "
As part of the deal for his guest appearance on the program, the WB (which, like PEOPLE, is part of AOL Time Warner) will run a public service announcement for the Christopher Reeve Paralysis Foundation at the conclusion of the episode.
Reeve was a little-known stage actor in the late '70s when he was catapulted to fame in the 1978 Christmas movie "Superman," which also spawned three sequels, all starring the tall, dark and handsome Reeve as the Man of Steel.
In 1995, the star was thrown from a horse in a riding accident near Charlottesville, Va., in a tragedy that left him a quadriplegic -- and a fierce fighter on behalf of research to help solve the problems of spinal cord injuries.
Reeve is said to be a fan of "Smallville," which is now in its second season as one of the WB's top-rated shows. It stars Welling as a teenage Clark Kent coming to grips with his superhuman strength on his way to adulthood and his campaign to fight for truth, justice and the American way.
