The geeks are set to descend on Sydney in June with the first line-up for the Supanova Pop Culture Expo announced today.
Hollywood starlet Hayden Panettiere is one of the headlining guests, along with Christopher Lloyd who played Doc Brown in the classic Back to the Future films.
Panettiere is best known for her role on TV series Heroes and most recently in Scream 4.
It’s back to the Batmobile for Yvonne Craig, the original Batgirl from the sixties TV series starring Adam West.
Craig is returning to Supanova after being a crowd favourite in 2002.
Other guests include Michael Rosenbaum, who played Lex Luthor in Smallville, Mercedes McNab, remembered as Harmony from Buffy and Angel, and Bob Wall from cult martial arts films Way of the Dragon and Enter the Dragon.
Best-selling novelist Christopher Paolini is set to be a favourite amongst the younger audience for his novels Eragon and Brisingr.
Comic book creators David Mack (Kabuki series) and Jim Cheung (Scion, Young Avengers) are set to be fanboy favourites.
Supanova 2012 kicks off in Melbourne and the Gold Coast next month, before a new line-up of guests come to Sydney, Perth, Brisbane and Adelaide in June.
Supanova is on at The Dome, Olympic Park on June 16 and 17.
