Steven Spielberg and George Lucas have worked in tandem on the last four Indiana Jones films—with Spielberg handling the visuals and Lucas in charge of the script. While that arrangement worked like a charm for the first three archaeological adventures, Spielberg admits there were ... problems ... with Kingdom of the Crystal Skull.
While talking to Empire Magazine about Tintin, Spielberg mentioned that Lucas is hard at work on the story for Indiana Jones 5—and took the time to explain his feelings about the oft-criticized Indiana Jones and the Kingdom of the Crystal Skull:
"I'm very happy with the movie. I always have been ... I sympathise with people who didn't like the MacGuffin because I never liked the MacGuffin. George and I had big arguments about the MacGuffin. I didn't want these things to be either aliens or inter-dimensional beings. But I am loyal to my best friend. When he writes a story he believes in—even if I don't believe in it—I'm going to shoot the movie the way George envisaged it. I'll add my own touches, I'll bring my own cast in, I'll shoot the way I want to shoot it, but I will always defer to George as the storyteller of the Indy series. I will never fight him on that."
However, Spielberg can't quite defend everything about Skull. He even agrees with that most notorious fan complaint:
"What people really jumped at was Indy climbing into a refrigerator and getting blown into the sky by an atom-bomb blast. Blame me. Don't blame George. That was my silly idea. People stopped saying 'jump the shark.' They now say, 'nuked the fridge.' I'm proud of that. I'm glad I was able to bring that into popular culture."
Well, I suppose it's nice to be proud of something Crystal Skull-related.
