Comicpalooza has snagged the ultimate Aliens.

The state's largest comic and pop culture confab announced Wednesday that the cast of the classic 1986 sci-fi thriller, Aliens, will be featured guests at this year's session, to be held June 17-19 at the George R. Brown Convention Center. Stars Sigourney Weaver, Bill Paxton, Paul Reiser, Carrie Henn, Michael Biehn, Jenette Goldstein, Lance Henriksen, and Mark Rolston will be on hand to greet fans and celebrate the 30th anniversary of James Cameron’s blockbuster hit movie in their first public cast reunion.

Weaver was nominated for an Oscar for her role in Aliens, in which she played the role of Warrant Officer Ellen Ripleyk, who battles with an extraterrestrial lifeform, commonly referred to as "the Alien." She originated the role in the 1979 film, Alien, directed by Ridley Scott, and earned much praise for her pioneering portrayal.

"Aliens is one of the movies that defined the '80s and it was a watershed decade for action and science fiction movies," Comicpalooza founder John Simons tells CultureMap.

The festival lineup also includes Underworld star Kate Beckinsale, The Walking Dead's Lennie James, Lou Ferrigno (The Incredible Hulk), Eliza Dushku (Buffy the Vampire Slayer, Angel), Walter Koenig (Star Trek), Kel Mitchell (Nickelodeon’s Game Shakers), David Prowse (Darth Vader), New York Times best-selling authors Mercedes Lackey, Leslie Klinger, and Sherrilyn Kenyon as well as comic book greats Adam Kubert, John Ostrander, and Mike Zeck.

Normally held on Memorial Day Week, Comicpalooza has moved to the mid-June date because the convention center was previously reserved for Memorial Day, but Simon says the event plans to move back to its usual spot on the calendar in 2017. Last year Comicpalooza drew more than 40,000 visitors who booked more than 16,000 hotel rooms.
