If you have HBO, tonight you'll have no complaints. The premiere of the latest HBO docudrama, "Citizen X," is a $l wonderful detective story -- and a highly unusual one, since it's about the search for a serial killer within the Soviet Union. However, if you don't have HBO, tonight in prime time you have ABC's "The Marshal," and a network telecast of "Adventures of Huckleberry Finn," and not much else.
* "The Adventures of Huck Finn." (8 p.m.-10 p.m., WMAR, Channel 2) -- It was a dead giveaway that this 1993 movie wasn't going to be exceptionally faithful to Mark Twain's masterpiece when it couldn't even get the title right. (There's no "The" in the book's correct title, and it's "Huckleberry," not "Huck.") But with Elijah Wood of "The Good Son" as Huck, and with Courtney B. Vance as Jim, this version has a lot more intelligence and sensitivity than many previous film and TV adaptations. Robbie Coltrane and Jason Robards have a good time as the Duke and King, respectively, and Ron Perlman, formerly of TV's "Beauty and the Beast," presents a beastly depiction of Huck's drunken Pap. Watch with your kids, or even without them. ABC.
* "Touched By an Angel: Miracles in Disguise." (9 p.m.-10 p.m., WJZ, Channel 13) -- This series returns to CBS, with an episode featuring two former series stars making temporary TV returns: Marion Ross, formerly of "Happy Days" and "Brooklyn Bridge," and Malcolm-Jamal Warner, formerly of "The Cosby Show." CBS.
* "The Marshal." (10 p.m.-11 p.m., WMAR, Channel 2) -- Cathy Podewell, formerly J.R. Ewing's young bride on the last seasons of "Dallas," guest stars as a woman with a much less innocent past. ABC.
* "Saturday Night Live." (11:30 p.m.-1 a.m., WBAL, Channel 11) -- George Clooney, as guest host, makes his third NBC series appearance in as many days. On Thursday night, he appeared in both his own series, "ER," and as a guest on "Friends." One sitcom, one drama, one variety show -- not bad variety for a few days' work. The musical guest is the Cranberries. NBC.
* "Citizen X." (8 p.m.-9:50 p.m., HBO) -- There are four crisp performances, and lots of surprises and artistry, in this excellent, fact-based story that brings to mind "Gorky Park," but quickly stands on its own as a kind of "Quincy, K.G.B." Stephen Rea is the forensic pathologist who doggedly investigates a string of brutal murders, Donald Sutherland attacks his role of Mr. Rea's superior with gusto, Joss Ackland attacks his bureaucratic role with bravado, and Max Von Sydow attacks his role with . . . Sydow.
* "Godzilla vs. Mothra." (midnight-2 a.m., TNT) -- In a way, this 1964 showdown between Japan's giant lizard and giant insect can be considered the Mothra of all monster-movie duels.
