They're not called special effects for nothing. Neither cheap to produce, nor easy to accomplish, they're what makes a movie magic. When the job's done right, the effects can be out of this world. Literally. Movies can take viewers -- to quote the animated toy Buzz Lightyear -- "to infinity and beyond."
So, what's your favorite F/X movie? Do you stand by animation master Ray Harryhausen's Clash of the Titans? Or were you seduced by Jessica Rabbit? Which simian proved more thrilling: King Kong or Dr. Zaius in Planet of the Apes?
Things aren't always what they seem, thank goodness.
