What is your question?
If you want this sentance revised, I think it should read: "When the movie Star Wars premiered in 1977, it's special effects were both revolutionary and surprising."

That's my opinion, but I'm just a high school senior and not a tutor. I hope this helps.

(And in the future, be sure to specifically state the nature of your post. It's hard to know what you need if you don't say. It it needs revised or proofed, say Revise or Proof at the begininng. If it's a question, word it like a question. You're more likely to get a helpful response.)
