Bill Cosby and Robert Culp will be reunited when Culp guest stars Thursday on “The Cosby Show.” He’ll play an old friend of Cliff Huxtable’s named Scott Kelly. The name is a joke in itself--a combination of the names each of them had when they co-starred in “I Spy” from 1965 to 1968.

Ed Asner, the star of NBC’s “Bronx Zoo,” will be seen as himself in an episode of CBS’ “The Popcorn Kid.” The show, due for broadcast April 17, has Asner showing up at the Majestic Theater in Kansas City for an “Ed Asner Film Festival.”

And speaking of old TV shows, NBC is reviving “This Is Your Life” as an hourlong special for April 19. Ralph Edwards, who introduced the show on radio in 1948 and then hosted a 1952-61 TV run, will be at the helm. Two celebrities will be treated to a trip down their own personal memory lane.

“Jesus of Nazareth,” Franco Zeffirelli’s much-admired miniseries about Christ, hasn’t been seen on network TV since 1984. It’ll be back this Easter, however. NBC plans to broadcast the eight-hour production over four nights, April 12-15. The cast includes Robert Powell as Jesus, Olivia Hussey as Mary, Rod Steiger as Pontius Pilate and Michael York as John the Baptist.

Louis Gossett Jr. and Malcolm-Jamal Warner of “The Cosby Show” are teaming for “The Father Clements Story,” a movie for NBC. Gossett plays a priest in Chicago who attempts to jolt the community into awareness of the plight of the homeless by adopting a young man (Warner).
