Suit up and stay up to watch your favorite sci-fi TV series.

Gemini and Scorpio, local purveyors of steampunk and fantasy, are holding a screening of episodes — possibly the whole season — of “Firefly,” a sci-fi series that was cancelled but not forgotten, at their Gowanus rooftop, for an all-night fan fest.

Why “Firefly”?

Not many television shows with a partial-season 12-show run could garner widespread celebration a full decade later.

“Firefly had that cult following from the very beginning,” said Larisa Fuchs, who is a co-founder of party and production company Gemini & Scorpio. “It’s such high camp and great characters and fun adventures. There’s so much fun that’s often missing from that kind of sci-fi fantasy.”

First of all, it was written and directed by Joss Whedon, who also created “Buffy the Vampire Slayer,” “Angel,” and “The Avengers” and is revered as a veritable god among sci-fi geeks.

And the show, which follows a group of 26th century rebel soldiers turned space pirates, is a cerebral and sexy melding of the Western and sci-fi genres, full of witty dialogue and comedic tension.

Of course, in true Gemini and Scorpio (and sci-fi geek) form, there will be plenty of dressing up for the occasion. Dressing up isn’t required to attend, but it is recommended. If the weather on the roof doesn’t cooperate, the screening will be moved to the loft downstairs. If they do end up screening the whole season, which seems likely, the party could go until early the next morning.

Firefly screening (RSVP to get address. www.geminiandscorpio.com/events.html) Sept. 15, 7 pm–7 am. $10.
