Ted Turner offers two major productions, "Young Catherine" and "Voice of the Planet," to his cable viewers this week. For reasons unknown, the two overlap, with the two-part, four-hour "Young Catherine" premiering on Sunday at 8 p.m., and concluding Monday at 8 p.m. on TNT, while the five-part, 10-hour "Voice of the Planet" begins Monday at 8:05 p.m. on TBS and runs through Friday at the same time.

"Young Catherine," starring Vanessa Redgrave, Christopher Plummer, Franco Nero, Maximilian Schell, Marthe Keller, Mark Frankel and Julia Ormond, in the title role, was filmed entirely in the Soviet Union.

The story focuses on the early life of Catherine the Great, who was a German teenager named Sophie when Russian Empress Elizabeth chose her at age 16 to marry her nephew, the successor to the throne. With her mother (Keller), Sophie leaves her Prussian homeland and arrives in St. Petersburg, where she must convert to the Russian Orthodox religion, endure a loveless marriage and outsmart those who who would try anything, even murder, to keep her from the throne.

Encores: At 10 p.m. Monday at Tuesday. Also both Parts I and II, Thursday at noon, and Sunday, Feb. 24, at 2 p.m.

"Voice of the Planet" is different than previous ecology specials. Based on Michael Tobias' book of the same name, the series deals with a disillusioned author/ecologist (William Shatner) who is taunted by persistent messages on his computer. That viewpoint comes from Gaia (voiced by Faye Dunaway), the spirit of Earth, offering provocative insights in how "Mother Earth" feels about over-population, sex, pollution, survival and her human children.

Sunday on The Disney Channel at 9 p.m. another in the popular "Going Home" series. This time it's "The Bee Gees: Going Home," featuring the five-time Grammy-winning Brothers Gibb -- Maurice, Robin and Barry -- with personal interviews and clips from a recent globe-spanning reunion tour.
