On The Weekend Watch:
INTO THE SUNSET -- The tube's last western rides off the air tonight (at 8, Channel 13), with a special two-hour final episode of "The Young Riders." With the Civil War impending, Cody (Stephen Baldwin) enlists as a Union scout, while Hickok and The Kid (Josh Brolin and Ty Miller) come to blows over their conflicting allegiances. But there's a wedding, too, between The Kid and Lou (Yvonne Suhor).
WOOOOOOO! -- The spirit of Mr. Spock, actor Leonard Nimoy of "Star Trek," materializes as host of "Haunted Lives: True Ghost ,, Stories," a CBS special Friday (at 8, Channel 11), repeated from 1991. Psychics help re-enact the spooky events.
A ROYAL TRAGEDY -- Daytime talk show host Sally Jessy Raphael mines the tabloid agony in prime time Friday on Fox (9 p.m., Channel 45) with "Di: Prisoner in the Palace." The show is said to offer "a rare glimpse into the private life of the kindergarten teacher turned princess who captivated the world with her beauty and charm." Now, of course, she's captivating the world with tales of eating disorders, attempted suicide and marital discord.
LET THE GAMES BEGIN -- That's the "XXV Olympic Summer Games," of course, the quadrennial meeting of athletes from around the world. The first of some 160 hours of NBC coverage from Barcelona, Spain, arrives on Friday (at 9 p.m. on Channel 2), with an "Olympic Preview." The parade of nations and opening ceremonies, with about 170 countries represented, highlight Saturday, and just as CBS sent "This Morning" host Paula Zahn to the Olympic Winter Games, NBC adds "Today" co-host Katie Couric to the coverage team headed by Bob Costas.
THE MOVIE MARQUEE -- In Olympics counter-programming, two movies on Saturday evoke memories of TV's past. At 8 o'clock on CBS (Channel 11), James Arness once again plays Dodge City Marshall Matt Dillon in "Gunsmoke: To the Last Man," a 1991 reprise film. And at the same hour on Channel 54, Raymond Burr is once against the most successful defense attorney ever in "Perry Mason: The Case of the All-Star Assassin," a 1989 edition of the periodic movies.
A LIFE ON STAGE -- English actor John Gielgud -- remember his droll role as Dudley Moore's butler in "Arthur"? -- reviews his distinguished career Friday in the latest edition of "Talking With David Frost" on PBS (at 10, Maryland Public Television). And he says he did the "Arthur" role as a joke. Still performing, the actor is 88.
BACK TO QUEENS -- The ongoing cable series "Best of Television," at 7 p.m. Sunday on the TBS basic service, highlights four episodes of "All in the Family." Norman Lear's frank, landmark comedy starred Carroll O'Connor and Jean Stapleton and added the term "dingbat" to common parlance.
