Honestly, I didn't know when I first saw it in 1995. I guess I was lucky... except that my stupid mother kept telling me while I was watching the movie, "I'm pretty sure that Darth Vader is Luke's father." Thankfully, I was so young and so not trusting about my mom's knowledge of anything that I flat out rejected it as being true. And so when I saw it, it was still a shock. I was about to eat crow, but I told myself that it's possible that it could have been a lie.
