You can almost see scientists rubbing their hands (or groaning) whenever a new Hollywood film rolls out, riddled with scientific errors. But one astronomer recently voiced a possibly blasphemous suggestion – maybe it's ok if a movie flubs the facts, as long as it gets the big picture right about science and scientists.

Seth Shostak of the SETI Institute comes with his own experience on Hollywood sets, having served as scientific advisor on the 2008 remake of The Day the Earth Stood Still. His biggest problem wasn't with the alien technology of Klaatu, the extraterrestrial harbinger of doom played by Keanu Reeves. Instead, he fought for the filmmakers to stop showing the scientists as number-crunching stereotypes.

San Jose State University is soon going to start offering a class called "Physics of Animation," that aims to teach future animators the proper way to render a leaf falling to the ground or a person walking with a realistic gait. Or a kung-fu fighting panda getting launched into the air by a furry little creature.

Physics is a key element of realism, says the course's professor, physicist Alejandro Garcia. Any movie-viewer can spot bad physics, though they might not always recognize what's bothering them. And for all the progress that has been made in animation in the last decade, and all the science homework that effects experts say they do prior to creating scenes, most movies still let through a glitch or two that makes the attentive viewer wince.

In the world of cinematic science fiction one of the most appealing themes involves a universe brimming over with intelligent life. In this imagined future (or past) humans interact with alien friend and foe because they've at last hammered down the ability to travel to distant stars and galaxies, and, yes, "to boldly go where no man has gone before. Having grown up on the original Star Trek series, observed the effect of the Star Wars movies on the zeitgeist of movie-going generations and enjoyed sci-fi soap operas like Battlestar Galactica, I have to admit I wish we could make it happen; no matter the odds.

When we spoke with Peter Segal—director of the upcoming film Get Smart—for our Sci-Tech Summer Movie Guide, he knew straight off that he had to play up the technology in the comedic spy caper. "We knew getting into this that the gadgets are really important," he says. He couldn't tell us about all the tech tools in the film, but there's a clever update of the infamous "cone of silence," and the movie features exploding cuff links and dental floss, plus a tooth radio.

Filming conventional high-speed action fare is hard enough, but to bring the classic cartoon Speed Racer to life, the Wachowski brothers had to contend with 300mph racecars sporting fanciful features like robotic reconnaissance pigeons and wheels that can rotate 180 degrees. With 2,300 visual-effects (VFX) shots—twice as many as last year’s eye-popping 300—it heralds the future of summer-blockbuster fare: The entire movie, aside from the human actors, exists only in a computer.

Afghanistan. A hidden bunker. Four men with rifles guard a thick, rusted steel door. Bam! A huge fist pounds against it—from inside. Bam! More blows dent the steel. The hinges strain. The guards cower, inching backward. Whatever's trying to break out is big. And angry.

Spiderman, Batman, the Fantastic Four, Ironman—seems like every time we go to the movies, there's some guy in a unitard saving the world with acts of unnatural physics. We realize that these are works of fantasy, so we don't get too upset when the science portrayed in them comes from some alternative universe.
