The new sci-fi series The Invisible Man (8 p.m. Fri. ET/7 PT, Sci-Fi Channel) stars Vincent Ventresca as a petty thief who can become invisible, thereby being of use to a shadowy government agency. Former President Gerald Ford is the subject of a new Biography (8 p.m. Fri., A&E). In back-to-back episodes of Making the Band (9 p.m. Fri., ABC), someone quits, leaving a void that can't be filled -- well, for an hour or so. CBS is rerunning the "Donnie Brasco"-inspired drama Falcone (10 p.m. Sat., CBS), which aired in the spring, to dismal ratings. Jason Gedrick plays an FBI agent, deep undercover within a Mafia family, who gets overly chummy with a sympathetic gangster (Titus Welliver). The mob stuff is pretty tame compared to what we've seen on "The Sopranos," and if you were a fan of the legendary CBS drama "Wiseguy," you'll be screaming, "Rip-off!" every other scene. Still, Welliver is one of those amazing TV actors who raise the level of everything they're in. The Simpsons (8 p.m. Sun., Fox) repeats the one where fame goes to Homer's head after he bowls a perfect game. On Sex and the City (9 p.m. Sun., HBO), Carrie's affair with the politician takes a kinky turn -- but does that surprise you? Behind the Music (9 p.m. Sun., VH1) is livin' on a prayer with a profile of big-haired New Jersey rockers Bon Jovi.

The four-part miniseries Gormenghast (8:30 p.m. Sat., BBC America) is an adaptation of Mervyn Peake's fantastical novel about the life of a young British earl surrounded by treachery and decadence.

The relationship between humans and equines is explored in the documentary In the Company of Horses (8 p.m. Sun., A&E). A gigantic sinkhole threatens to swallow New Orleans on the eve of Mardi Gras (and only rugged geologist John Corbett can stop it!) in the new cable disaster movie On Hostile Ground (8 p.m. ET/ 7 PT, Sun., TBS).
