Could there be a way to hypnotize myself so that I could forget the plot of a movie and watch it without knowing what happens?

My favorite thing about movies is the utter surprise I get when I find something out. Therefore, I would love to be able to hypnotize myself into forgetting what happens in a movie, so i'd be able to feel the joy I felt when I first saw it. I couldn't find any hypnosis on the internet that could do this, so if any of you know or would be willing to explain if that's even possible just let me know please. Thanks!
