Off the Wall: AMC's 'Rifelman' block

Off the Wall digs deep to find TV's most offbeat and/or obscure.

SINGLE WESTERN DAD Before AMC unreels its daytime western movie slate each Saturday, there's a TV lead-in -- "The Rifleman" (Saturday, 6 a.m.-8:30 a.m., AMC), the classic black-and-white half-hour about a widowed father (Chuck Connors) trying to teach his boy that might doesn't make right. (Except all those times he's forced to fire his gun, anyway.) Watch online, too, at hulu.com/rifleman.

AHOY, MATEY! While you wait for Johnny Depp's fourth franchise film to hit theaters Friday, watch his third, "Pirates of the Caribbean: At World's End" (Saturday night at 8, ABC/7). Or his first, "Pirates of the Caribbean" (Sunday at 8 p.m., ABC Family). Also on tap: the documentary "True Caribbean Pirates" (Saturday night at 8, History), profiling legendary names like Blackbeard and Calico Jack, and the season premiere of "The Real Story" (Sunday at 8 p.m., Smithsonian), seeking the historical fact behind Depp's Hollywood fiction.

HOW MUCH 'PSYCH' CAN YOU STAND? Find out with a 24-hour marathon of "Psych" (Sunday 6 a.m.-Monday 6 a.m., Sleuth). Fresh episodes premiere on USA this fall. Until then, try usanetwork.com/series /psych.

SERIES PREMIERES If your neighbors own lions, tigers or bears, these are the guys to call. "Wild Animal Repo" (Sunday at 8 p.m., Discovery) specializes in rescuing wildlife owned by people who shouldn't, and delivering the specimens to more suitable homes. "Off Limits" (Monday at 9 p.m., Travel) visits intriguing man-made sites to which the public normally has no access. The Los Angeles-shot premiere drops in at aqueducts and a secret Nazi compound. Next week: San Francisco. Sneak peek at travel channel.com.

LET'S X-RAY THE EARTH! Sure, why not? "X-Ray Earth" (Sunday 8-10 p.m., NatGeo) uses CGI to see what our planet would look like, inside as well as out. More on the show at natgeo tv.com/uk/x-ray-earth.

SEASIDE SALVATION OR BROOKLYN BOONDOGGLE? That's the question asked by "Last Summer at Coney Island" (Sunday at 10 p.m., WNET/13). Can this birthplace of modern American amusement be returned to its former recreational splendor? Or will its public playground give way to more commercial development? Trailer, info at last summeratconeyisland.com.

OSAMA CHRONICLE How did America find and kill the world's most wanted terrorist? "Killing Bin Laden" (Sunday at 10 p.m., Discovery) offers a minute-by-minute account of the dramatic Navy SEALs mission, plus back story about early intelligence and planning. More at discovery.com.
