“If ABC was courageous enough to put on Lost, they’ll be courageous enough to put on Flashforward.” That from David S. Goyer (Batman Begins), who reflected at Comic-Con today about the first time he peddled the high-concept series to ABC. Debuting Sept. 24, Flashforward differs from the novel of the same name by Robert Sawyer in that a global catastrophe gives people a sneak peek of their future six months ahead of time (as opposed to 21 years in the novel). But fear not, Sawyer fans: Goyer said Sawyer not only approved of the pilot but he’ll write a script for the first season.

Goyer promises lots of “Easter egg” surprises throughout the high-concept series (like a shout-out to Watchmen‘s D. Gibbons in the pilot) and adds the show has the potential to go on for years. “Every single man, woman, and child has a vision of the future,” says fellow exec producer Brannon Braga (24). “That’s 6.8 billion potential stories to tell…and a great syndicated package.”

Goyer assured the crowd that Flashforward is not trying to replace Lost. “Nothing will be the new Lost,” he says (though Flashforward does star Sonya Walger, who plays Penny on the series). “Lost was genre-breaking.”

Sadly, the producers wouldn’t give hints about what catastrophe actually causes the blackout, but he did give the crowd a good laugh about it. “Rush Limbaugh farted,” he cracked. “It’s a big ass.”

The producers also hinted about other projects in the works. Goyer said “We are musing…there is musing happening” over another Batman movie, and Guggenheim said he and Braga are talking to Marvel about a new project.

UPDATE: ABC just announced that former Lost star Dominic Monaghan will be joining the cast of Flashforward… though they offered no details about who he’ll play. Dare we hope Charlie had a long-lost twin brother?
