Brian Dennehy is back on TV, which usually is good news, and tonight's appearance is no exception. The nod for the most exceptional offering, however, probably goes to "Picket Fences," which has gotten, if anything, even stronger this season.
* "Family Matters" (8-8:30 p.m., WJZ, Channel 13) -- Taking its cue, or at least its concept, from certain movies starring Jerry Lewis and Cary Grant (independently, that is), tonight's "Family Matters" has ultra-nerd Steve Urkel (Jaleel White) drinking a potion that turns him into a --ing young sophisticate. ABC.
* "The Adventures of Brisco County, Jr." (8-9 p.m., WBFF, Channel 45) -- Sheena Easton guest stars as Crystal Hawks, a female bounty hunter, whose quarry is County himself. Bruce Campbell stars. Fox.
* "Boy Meets World" (8:30-9 p.m., WJZ, Channel 13) -- Here's an unusual guest shot: William Russ, best known for dramatic roles ("Wiseguy," for example), takes a comedy turn on tonight's "Boy Meets World." ABC.
* "Jack Reed: Badge of Honor" (9-11 p.m., WMAR, Channel 2) -- Brian Dennehy was good enough as Chicago cop Jack Reed in last year's successful NBC miniseries "Deadly Matrimony" to have a sequel TV movie to showcase the actor and character again. Also reprising the role from last season's drama is Susan Ruttan, formerly of "L. A. Law." Co-stars this time around include William Sadler, Alice Krige and Jo Anderson. NBC.
* "The X-Files" (9-10 p.m., WBFF, Channel 45) -- This might explain a lot: Tonight's "X-Files" suggests that an alien intelligence could be behind certain accidents in NASA's shuttle program. Earthbound intelligence, after all, is out of the question. Fox.
* "Picket Fences" (10-11 p.m., WBAL, Channel 11) -- Marlee Matlin, who was on "Seinfeld" recently, makes a guest shot as a modern female Robin Hood on tonight's "Picket Fences." The script, by series creator David E. Kelley, also features Chris Sarandon, as a fellow fugitive who, with Ms. Matlin's character, stages a bank robbery in Rome. CBS.
* "Dr. Giggles" (8-9:35 p.m., MAX) -- Larry Drake of "L.A. Law" is a real cut-up in this rather gruesome movie -- and one potential victim is played by Holly Marie Combs -- Kimberly Brock on
