Most recently, she's sharing her talents in I'm Not There - a film about the life of Bob Dylan, and she's uncannily compelling. I don't give a damn about Bob Dylan, but watching Cate's clips in the trailer makes me want to see the film.
Good thing she doesn't (seem to) have aspirations to be a cult leader - I would be unable to resist her (let's surmise...) maniacal machinations to control the world's soybeans.
You've heard the old saying "I'd listen to so-and-so read the phone book"? I'd pay to see the three hour documentary Cate Blanchett - Flossing and Tweezing.
