In an interview with Entertainment Weekly Cate Blanchett spoke about her experiences working with Steven Spielberg and Harrison Ford in Indiana Jones 4:

[What] can you tell me about the Indiana Jones film?
It’s phenomenal to be working with Harrison Ford and Spielberg and Karen Allen, all of whom were in one of the most amazing experiences of my childhood, watching that film. And then I’m stepping into the frame. It’s a real Zelig moment for me. It was really quite moving when Karen filmed her first entry into the film the other day. You know, Spielberg said, ”I feel so young!” [Laughs] It was fantastic.

And what is the Spielberg experience?
Look, he’s an absolute master. He knows the genre like the back of his hand, and he makes fantastic suggestions. He’s really fast and incredibly creative. Like, if a shot’s not working, he’d completely change it and do something equally as amazing. And it’s weird, because I feel like I know all the movies as an audience [member]. I know all the lighting, I know all the elements. But it’s coming together in a new way. And Harrison looks f—ing great.
