Superman and the Terminator have been knocked out, but Ripley has made it on to the semifinal round of The Greatest Movie Hero tournament. She's up against Indiana Jones -- but really, what chance does a whip-cracking archaeologist have against a woman who has beaten back an entire army of aliens?

Now more then ever, your vote decides who qualifies as the ultimate movie hero. So cast your vote then enter the sweepstakes for a chance to win $5000 for yourself and another $5000 for your favorite charity.

The finals begin next Friday. You can enter the sweeps daily to better your odds of winning.

When it comes to traveling through the final fronter, what would you rather be on board: the Millennium Falcon or the Starship Enterprise? And would either of them be any match for the gargantuan Star Destroyers of the Imperial Fleet?

Ripley and The Terminator (never mind Superman) are in the running. And while the odds might be against the scifi heroes, just because they're outnumbered, doesn't mean they're underdogs.

We're not even through February of 2008 and the rumor mill is hard at work on the slate of science fiction films coming in 2009.

First came the news that J.J. Abrams' Star Trek prequel would be pushed to next May, which had bookies and book nerds alike wondering how much damage it would do to Marvel's Wolverine spinoff. And now today brought news that McG's Terminator fourquel, starring Christian Bale and Sam Worthington, will also have a May 2009 release date. But which futuristic franchise has what it takes to win the month at the box office?

More than any other genre, science fiction has pushed the envelope for cinematic special effects. Sometimes the visual wizardry is more impressive than the movie itself. (See Independence Day.) Other times it's organic to the whole experience. (See 2001: A Space Odyssey.) So which is your favorite? Is it the unbelievable cityscapes of Blade Runner? Or do you prefer the steely killing machines of T2: Judgment Day? Can you remember what it was like the first time you saw the slimy Freudian-monsters in Aliens? Can you forget the stop motion magic of the original King Kong? Here's your chance to weigh in. Hundreds of people have done so thus far. The results might surprise you.

Let's face it. All robots are not created equal. Some have the ability to enslave galaxies; others merely sweep up the crumbs off your floor. Some feel no shame, exposing their gears and wires for all to see, while others hide behind a human (and often deceptively friendly) face. And who's to judge whether quality means the ability to speak all known languages fluently or the ability to hunt humans with infra-red vision? You are!

For AMC's Coolest Robot poll, the opponents are lined up for battle, with your votes and comments determining which artificial life form will be victorious. Currently Terminator's T-800 stands atop the heap of smoking rubble, but only time will tell whether a dark horse will unseat him. Will he meet his match with the Borg or Gynoid? Will Gort twist his arm until he hollers "Klaatu Barada Nikto"? Can a mere human mind comprehend the gravity of such an important matter? I guess we'll have to wait and see!

Science Fiction filmmakers are often presented with the daunting challenge of showing parallel worlds, far-away planets and futuristic dystopias. Movies illustrate these alien settings with everything from brightly-colored tunics to metallic codpieces. But one of the most memorable and iconic methods is the overly-stylized hairdo.

Genre heroes always manage to have great hair--whether they're battling an army of sword-wielding skeletons or flying through the sky chased by a swarm of frog-men. Halloween shops sell everything from Princess Leia style cinnamon bun curls to the black and white fright wig of The Bride of Frankenstein. But which coiff is your favorite?

Last week the Scanner reported rumors that metal thrasher and all-around-weirdo Rob Zombie was in talks to direct a sequel to Conan the Barbarian. Well, it now seems he is just one of the directors that has been approached about the loinclothed project. Neil Marshall, the Brit whose upcoming horror flick Doomsday looks, well, awesome, is in talks, as is Hitman helmer Xavier Gens. Rob and Xavier may have cooler names, but do they have the right stuff for the job?

Pictures from the new Indiana Jones movies are now cropping up like snakes in a tomb. In recent days we've seen glimpses of Harrison Ford holding a bazooka, the titular Crystal Skull, and of course Cate Blanchett looking extremely, well, Reichish, holding a sword against Ford's throat.

But she won't be the first woman to try to handle Jones' whip. Who do you think is the good Doctor's most eligible bachelorette?

1. Move over Da Vinci, the cast of Battlestar Galactica posed for a Last Supper portrait riddled with clues about the upcoming fourth and final season. Who does Chief Tyrol want to stab? Who's the final Cylon? Why is Caprica Six posing as Jesus?

2. What could be better than three new Terminator movies starring Christian Bale? How about an Animatrix-style tie-in, Termination, due to be released in 2009? We see no need to Fight this Future.

3. The force is strong with this 11-year-old Brit, who chivalrously used his plastic lightsaber to fend off attacks from a would-be assailant. "I have a very bad feeling about this," was heard escaping Han Solo's lips as geeks everywhere began strapping arsenals of Hasbro phasers and blasters to their belts.

4. Serve Jennifer Garner an extra-live portion of Gagh, because the actress has recently confided she wants to play a Klingon in J.J. Abrams' upcoming Star Trek remake.

5. Hayden Christiansen, the actor who transformed Darth Vader from a Dark Lord into a whiny zit-popper, set his sights on cyperpunk by signing on to tackle the lead role in an adaptation of William Gibson's genre-defining Neuromancer.

SciFi Dept Video: Kevin Maher, through his painstaking analysis of the 1980 SciFi musical The Apple, proves once and for all that American Idol is actually a means of controlling the proletariat via fascist propaganda.
