Atlanta’s coolest sci-fi convention DragonCon is just 16 days away and fans of “The Incredible Hulk,” “Dukes of Hazzard,” “Battlestar Galactica” (the original and the recent version) and “Star Trek” should be thrilled.

The convention is now at four hotels: The Hyatt, the Marriott, the Hilton and the Sheraton. It happens Sept. 4 to 7.

Among the attendees this year include:

— Leonard Nimoy, best known as Spock on “Star Trek”

— Charisma Carpenter, a star on “Buffy the Vampire Star” and “Angel”

— Edward James Olmos, played Admiral William Adama on the just ended “Battlestar Galactica.” His other credits include “American Family” and “Miami Vice.”

 — Patrick Stewart. Capt. Jean-Luc Picard in “Star Trek: The Next Generation”

— John Schneider. A North Springs High School grad, he is best known as Bo Duke on “The Dukes of Hazzard,” with a big role on “Smallville” as Clark Kent’s adoptive dad for 111 episodes.

— Catherine Bach. Daisy Duke on “The Dukes of Hazzard”

— Malcolm McDowell. Star of “Clockwork Orange.” Recently had a meaty role in “Heroes.” And the man who killed Captain Kirk in the film “Star Trek Generations.”

— Lou Ferrigno, “The Incredible Hulk,” who plays himself in “I Love You,Man” and recently helped Michael Jackson work out before MJ died. Rumors of him joining “Dancing With the Stars’ did not come to pass.

— Kate Mulgrew. Capt. Kathryn Janeway on “Star Trek: Voyager”

— Gil Gerard. Star of “Buck Rogers in the 25th Century”

— Richard Hatch. The original star of “Battlestar Galactica.” (No, not the naked guy and tax cheat from “Survivor”)

— Kristy Swanson. The original film star of “Buffy the Vampire Slayer”

— Traci Lords. Former porn star became a respectable actress.

— Terry Gilliam. Part of “Monty Python” and a director of films such as “12 Monkeys” and “Fear and Loathing in Las Vegas.”

— Barry Bostwick. Star of “Rock Horror Picture Show” and was in “Spin City.”

This is not San Diego’s ever-growing ComicCon, which is now a great venue for networks to promote shows such as “Lost,” “Heroes” and “Fringe.” Dragoncon gets none of that. Why? Mostly timing — and location.

Most actors are on the West Coast. Plus, all current shows will be production by the first week of September. So the show producers have to rely on oldies but goodies who don’t mind making a few bucks meeting with fans.

Each celebrity sets aside time to sit at the “Walk of Fame” where you can pay x number of dollars to get their autographs and in some cases, your photos taken with them. It’s a pretty brutally capitalistic place. Popular folks can charge more, lesser known celebrities far less. And if they overprice themselves or are really have lost their luster, they might just be sitting them forlorn, alone.
