Friday TV: Another Comic-Con; Ozzy, Leguizamo Portraits

Leave it to the week of Comic-Con for a one hour special on the obsessives who hang out at comic book shops.

Never mind that Kevin Smith pretty much covered the same subject in his fairly entertaining “Comic Book Men.” But the one hour “Comic Store Heroes” (National Geographic, 8 p.m.) follows several stories at Midwotn Comics in New York City as it prepares for its own New York Comic Con.

So there’s a forced competition among employees, pranks, buying top dollar comics from the public for high resale. Ther’s a quest for a particular title: “Hot Stuff” No. 1. And the author of a new comic book who wants to get it in stock. Could a series be next?

A season finale comes for “The Ricky Gervais” (HBO, 9 p.m.) in which Karl talks about how evolved every species is becoming. Everybody but him.

What better place to go “Chasing UFOs” (National Geographic Channel, 10 p.m.) than Roswell, N.M. This week was the 65^th anniversary of the crash there that led to rumors of a UFO landing.

Ben DeJesus’ film “John Leguizamo’s Tales from a Ghetto Klown” (PBS, 9 p.m., check local listings) gives a behind the scenes look at the actor and playwright as he prepared his 2011 one-man show, “Ghetto Klown” which he took to his native Colombia and performed in Spanish. Leguizamo’s voice is also in the new “Ice Age” movie (but they probably won’t mention that). It’s part of PBS Friday Night Arts Festival.

The metal pioneer turned reality show clown is profiled in the feature “God Bless Ozzy Osbourne” (Showtime, 9 p.m.), a bio film by Mike Fleiss and and Mike Piscitelli that was produced in part by son Jack Osbourne.

Paul Rudd guest stars on “Comedy Bang! Bang!” (IFC, 10 p.m.).

Slater’s 10 year marriage is on the rocks, perhaps because he has been referring to it as the “Louisiana Lockdown” (Animal Planet, 10 p.m.).

Chris Cuomo reports on summer vacation pitfalls on a two hour “20/20” (ABC, 9 p.m.).

To mark what would be his 100^th birthday, Turner Classic Movies shows four films by Sam Fuller: “I Shot Jesse James” (8 p.m.), “Park Row” (9:30 p.m.), “Shock Corridor” (11 p.m.) and “The Naked Kiss” (12:45 a.m.).

Stage 12 of the Tour de France (NBC Sports, 8 p.m.) from Saint-Jean-de-Maurienne to Annonay Davezieux.
