The concept of messing with memories is one that's been at the heart of some great sci-fi stories for decades, and it speaks to the very core of humanity—we are what we experience, but what if we didn't really experience it all?
From fake memories to brainwashing clones, there have been all sorts of twists on the classic memory-wipe concept. It makes for high drama, and when done well, can make you wonder what's real and what isn't.
With Len Wiseman's remake of the 1990 mind-wiping classic Total Recall opening this weekend, we thought it'd be a good time to look back at some of the best memory-wiping and reprogramming sci-fi flicks out there.
So enjoy—and maybe you'll remember a few of these.
