BEST BETS FOR SATURDAY, JULY 31, 2010

	PERSONS UNKNOWN NBC, 8 p.m. ET Joe (Jason Wiles) had a tough time of it last week, being interrogated by his fellow townspeople to determine his role in the mysterious mass-abduction conspiracy. Tonight, he has an even tougher time of it. In a plot that sounds closer than ever to the classic series The Prisoner, Joe is picked up by the village officials, pumped with hallucinatory drugs and interrogated, with hopes of altering his memories, behavior and personality.
	BAD DAY AT BLACK ROCK TCM, 8 p.m. ET In this 1955 John Sturges movie, Spencer Tracy plays a guy so tough, and so feared, he can take on his adversaries one-handed. And has to, because he happens to be one-armed. But, as he proves the first time he shoots someone, one-armed is better than unarmed. Ernest Borgnine co-stars.
	BEING HUMAN BBC America, 9 p.m. ET Tonight’s second episode of the new season has Annie falling in love with a human. Her relationship doesn’t have a ghost of a chance: She is, after all, a ghost herself. And the guy? He may turn out to be, like so many new suitors, less than human himself.
	EXTRACT Showtime, 9 p.m. ET Mike Judge wrote and directed this 2009 dark comedy, in which a meek guy named Joel (Jason Bateman) has an unfulfilling job (running a small factory), a seemingly unfaithful wife (Kristin Wiig), and an attractive employee (Mila Kunis) whom he’d like to know better. His bartender (Ben Affleck) proposes a novel solution: hire a gigolo to seduce his wife, after which Joel can embark on his own affair relatively guilt-free. The plan doesn’t work, of course – but this movie does. Others in the cast include a pair of Simmons: J.K., from Oz and The Closer, and Gene, from, uh, KISS.
	SURROGATES Starz, 9 p.m. ET This 2009 movie plays with the same inhabit-an-alternate-body-and-world premise of Avatar, but much less successfully – though, for sake of comparison on a slow Saturday, it’s not without its own little pleasures. Bruce Willis plays an FBI agent investigating a murder in a machine-generated fantasy world where, in theory, no deaths should be “permanent.” The twist: In the world he’s investigating, the agent, and Rahda Mitchell as a fellow investigator, look as plastically attractive as they do in the accompanying picture. In “real life,” not so much.
	FUR: AN IMAGINARY PORTRAIT OF DIANE ARBUS Sundance, 10 p.m. ET This 2006 movie was the little-seen follow-up film by director Steven Shainberg and screenplay adaptation author Erin Cressida Wilson, who teamed in similar capacities for 2002’s impressively quirky Secretary, starring Maggie Gyllenhaal and James Spader in an unusually charged love story. This film takes “quirky” to a whole new level, as warned by its subtitle. Nicole Kidman stars as Diane Arbus, in a somewhat surrealistic drama that recounts her initial attraction to, and adoption of, photography as a career. Co-stars include Ty Burrell (of ABC’s Modern Family) as Allan Arbus, and Robert Downey, Jr., who – pre-Iron Man – plays Lionel Sweeney, a man with a wolfman-like hair condition. (Which means, for his condition, he needs lots of conditioner.)
