If you want to be entertained by TV tonight, and don't have cable, you have only a few hours to get it installed. Otherwise, the night's a near-total wash.
* "Fudge-A-Mania" (8 p.m.-10 p.m., Channel 2) -- For fans of Judy Blume's books, this ABC made-for-TV movie, the first in an XTC occasional series, is the biggest news of the week. Coming from Steven Spielberg's Amblin Productions, it's easily the most substantial and welcome of the new "ABC Family Movie" offerings to date this season, and Luke Tarsitano, as Fudge, should please youngsters. Among the supporting cast, a mini-Brady Bunch: both Eve Plumb and Florence Henderson are on board. ABC.
* "TekWar" (7 p.m.-8 p.m., USA) -- After four TekWar movies based on the sci-fi novels credited to William Shatner, the concept is launched as a weekly series -- with an episode strong enough to vault TekWar above, say, Babylon 5. Greg Evigan returns as future cop Jake Cardigan, with a strong guest performance by Jennifer Griffin and a surprisingly effective guest appearance by Mr. Shatner himself.
* "Castle Keep" (8 p.m.-10 p.m., A&E;) -- Movie give back.
* "Grumpy Old Men" (8 p.m.-9:45 p.m., HBO) -- Jack Lemmon and Walter Matthau, the famed cinematic "Odd Couple" team, return in this 1993 comedy, crabbier than ever and with comic support by Ann-Margret and Daryl Hannah.
* "Philadelphia" (8 p.m.-10:10 p.m., SHO) -- Tom Hanks won an Oscar for his role in this 1993 movie -- and doubtlessly will be up for another thanks to his work in 1994's "Forrest Gump." Watching this role, and remembering that one, demonstrates precisely how much range Mr. Hanks has. Sadly, dozens of the HIV-infected extras (and some featured supporting players) have died since this film was released.
* "Super Dave's Vegas Spectacular" (10:30 p.m.-11 p.m., USA) -- Bob Einstein, as Super Dave Osborne, has gotten more mileage out of a comic alter-ego than anyone since Andy Kaufman and Pee Wee Herman -- and has fared far better than both. Tonight marks the launch of yet another new "Super Dave" series, this one suggesting the Las Vegas equivalent of a "Larry Sanders Show"-type comedy show.
* "Acting on Impulse" (12:30 a.m.-2:05 a.m., SHO) -- Linda Fiorentino, who got such raves from film critics this year, is on view in this 1993 cable movie, playing a "B movie" actress who gets involved in murder.
