From the IMDB:
Movie mogul George Lucas refuses to give up on recruiting Sean Connery for the fourth Indiana Jones movie, despite the Scottish star’s reluctance to sign on as the adventurer’s father. Connery has been linked to the upcoming fourth Indiana Jones movie, but insists he’s not that interested in reprising his role as Henry Jones from Indiana Jones & The Last Crusade. That hasn’t stopped persistent Lucas, who says, “We’re still trying.”
Now, excuse me for being skeptical… but didn’t you tell us that the script was all finished and that you’re starting film in less than 2 months? Umm… so Mr. Lucas… I know you’re not going to replace Sean Connery as Dr. Jones Sr…. and I highly doubt you’re panning on having Sean Connery for a 2 minute cameo… soooo… ummm… what gives?
Exactly how “finished” is this script that you’re telling us is ready to go? Or is Connery’s role in the film so insignificant that at the last moment they could be included or excluded? If that’s the case… it doesn’t say much for the quality of the story if you have entire characters in the final draft whose appearance or disappearance are totally inconsequential.
The story also went on to talk about Lucas being surprised by Spielberg’s decision to cast Cate Blanchett:
Lucas admits he was stunned when director Steven Spielberg told him he wanted to sign Cate Blanchett as Jones’ love interest in the new film. He tells newspaper USA Today, “That’s who my director wanted and I always bow to the wishes of my director. I approved it because she seemed like a good idea.
I’m sure that the fact the “Director” in this case is Steven Spielberg had something to do with being willing to “bow to the wishes”.
