From filmmakers employing decades-old practical tricks rather than cheaper and more time-effective CGI, to mind-blowing stunts that were somehow achieved without a green screen and, yes, even the occasional sneaky use of CGI itself, these movies represent the truly escapist, transformative power of special effects.
It's easy to see how everyone was fooled when these movies first came out, and even to this day, more casual viewers may still not be aware of exactly how these all-timer effects were pulled off...
