Lucas explains to the AP: “They wanted to go off on some other tangent. I said, ‘I’m not going to do that. I’m going to stick with this no matter what, so we either do this or we don’t. That’s it.’ Finally, we got something that we could all compromise on and all be happy with. It wasn’t quite as wacky as I wanted it to be, but it still is subtle and nice and works really well and has the same idea behind it.”

Wow, if it wasn't for Spielberg and Harrison's protest over the story, this film could have been worse.
