"It's really about the script," said Marshall. "Once we see that, we'll see. We're not going to wait another 20 years. We'd all love to make another one. I'm anxious to hear the idea!" But he quickly added that he really didn't know what Spielberg was cooking. "Until there's a script, nothing's definite. I haven't heard the idea." (He should ask LaBeouf. I bet he knows.) Marshall also confirmed that Lucas, Spielberg, and Ford were equally eager to return for a fifth outing. "Yeah. We had a great time making the last one and, as Harrison said, we need to make this one soon. We're not getting any younger."
While talk is talk, and plans vanish, bear in mind that they were already chattering about a fifth outing before Kingdom of the Crystal Skull hit theaters, and were still dreaming of it after, despite the negative reviews and fan backlash. I have no doubt it'll happen regardless of what the fans say or think. When it does, that shrieking sound you hear? That'll be the death cry of my fangirl soul ... and I'm sure it won't be the only lament visited upon the heavens.
