Off the Wall: Syfy unearths a chiller

Off the Wall is totally ready to chill.

ALIEN ICE CREATURE! That's the latest brainstorm from Syfy's Saturday Original Movies franchise. "Frost Giant" (Saturday at 9 p.m.) stars Dean Cain as an explorer whose dig through the permafrost unearths a monster that starts sucking away the planet's heat energy. (Hey, no global warming!) Preview at syfy.com/movies.

CAR SPEAKER NOT NEEDED MGMhd's Saturday night Drive-In triple feature revisits the outdoor movie experience with vintage flicks. This week features the remastered high-def premiere of John Severson's '70s surf saga "Pacific Vibrations" (Saturday at 10 p.m.), followed by Frankie and Annette's '60s romp "Bikini Beach" (midnight) and the cheesy '70s scarefest "Tentacles" (2 a.m.). Film clips at mgmhd.com/drivein.

CANINE CREATION How can St. Bernards and chihuahuas possibly be part of the same species? "And Man Created Dog" (Sunday 9-11 p.m., NatGeo) explains it all - how primitive humans started domesticating wolves who would genetically evolve into the wide range of animals who now serve as man's best friend and working companion. Video at natgeotv.com/episode/and-man-created-dog-3136.

KIDS WITH JOBS Kids don't just deliver newspapers anymore. "Workin' It" (Sunday at 9 p.m., Nickelodeon), the latest "Nick News" report, visits with kids who act on Broadway, cook in restaurants, announce baseball games and create computer apps. More at nicknews.com.

MUSIC VIDEO DEDICATIONS All you need is Facebook. The new afternoon hour "Tag Your Tune" (weekdays at 4 p.m., fuse) plugs into the social-networking site, where viewers can both dedicate videos and learn what time their selections will air. Connect at fuse.tv.

AWARDS ALERT Katy Perry co-hosts "Teen Choice 2010" (Monday 8-10 p.m., Fox/5) with the guys of "Glee" - Chris Colfer, Kevin McHale, Cory Monteith and Mark Salling. Also announced to appear on the 12th annual teen-vote bash: Jane Lynch, Taylor Lautner, Robert Pattinson, Ellen DeGeneres, Zac Efron, David Archuleta, Jim Parsons, Kristen Bell, Ryan Sheckler and at least three Kardashians. Watch "green carpet" stream at teenchoiceawards.com.

REAL WORLD PREMIERES Consider it the real-life version of "Huge," as "Too Fat for 15: Fighting Back" (Monday at 8 p.m., Style) documents life at a North Carolina weight-loss boarding school. "Wild Nights With Mireya Mayor" (Monday at 9 p.m., NatGeo Wild) explores wildlife in urban centers like New Orleans. "World's Wildest Encounters" (Tuesday at 10 p.m., NatGeo Wild) follows Andreas Kieling as he tries to film elusive animals like Alaskan grizzlies. Even wilder, probably, is listening in on loudmouth Jets coach Rex Ryan during team practice in the new weekly digest "Hard Knocks: Training Camp With the New York Jets" (Wednesday at 10 p.m., HBO).

SOAP STARS SHINE Vanessa Marcil (who now adds her married name, Giovinazzo) returns as Brenda on "General Hospital" (Wednesday at 3 p.m., ABC/7). But first, ABC celebrates with vintage Brenda episodes throughout the previous day's soap block (Tuesday 1-4 p.m., Ch. 7), and SOAPnet remembers Brenda's men from 1996-2002 episodes (Tuesday 8-11 p.m., SOAPnet). If that's not enough "GH," the daytime drama welcomes Adrienne Barbeau ("Maude") to its cast on Thursday. All you need to know at abc.com/generalhospital.
