Say what? Don't worry, Lucas assures us that not only was Connery substituted, but so was his character. So, the replacement isn't Henry Jones (aka Indy's dad), it is some other minor character who somehow fulfills the same narrative role. In the end, Lucas claims it was better this way, because fans would have seen Connery early on and then hoped he was going to appear throughout. The original script, though, had Henry Jones show up only for a short part. Could this substitute character be Jim Broadbent's academic colleague at Yale? Makes sense. Check out Lucas' exact reasoning for why the switch was better in TV Guide's interview.
In more tune with this morning's leak, MTV Movies Blog yesterday posted some words from Cate Blanchett regarding her character. Of course, the actress was more tight-lipped than Tyler Nelson, and only confirmed that regretfully she was not a romantic interest for Indy and nowhere in the script did it call for she and Harrison Ford to share a kiss. So, before today's spoilers, it was already speculated with strong evidence that Blanchett would be playing some sort of villain.
