Ever since the Star Wars: The Force Awakens premiere, many people have expressed their frustration at other people revealing spoilers of the film before they have seen it.
Here is what he said in full:
Stop that. Don't do that. Please don't do that. Don't do that, because people are paying to get in and they should experience the movie. Talk about it later. Please. Don't tell people what happens before they go into the theatre.
You paid for it. So let them pay for it. And let them enjoy the full satisfaction in having earned the experience, because you want your audience to have an experience, not have something served to them. There's a menu, you choose what you want to take from it. But you don't want to spoil it.
