She’ll play the money-voiced object of Leonardo DiCaprio’s affection, and second cousin to the narrator, Nick Carraway, rumored to be Tobey Maguire.

Iiiiiiiinteresting. Mulligan’s a terrific actress, but the thing about Daisy is that she’s both alluring and kind of awful. We have to see not only why Jay would love her — and obsess over her — but also why she’d become a symbol for the hollowness of the American dream. Daisy’s vain and capricious, but previous adaptations have also made her seem completely vacant, too. Gushing about those beautiful shirts? I can totally picture Mulligan bringing the right tinge of seriousness to the moment. (It’s harder than it sounds. I’m looking at you, Mia Farrow.) People are intensely drawn to Daisy, but that magnetism comes at a price. Just ask Myrtle.

Oh yeah! Myrtle! Who’s going to play her? My vote is for Abbie Cornish. She’s still not a full-on star, which is too bad because she was fantastic in Bright Star, and I think she can pull off that sort of blustery, sexy thing with aplomb. Can’t you see her paired with Ryan Gosling as George? He does that wounded/vengeance-y thing so well.

Which brings us to Tom. He’s a former football player, and he’s physically intimidating — but also a total putz and adulterer. He’s a tiny bit older than Nick, who celebrates his 30th birthday in the book, which makes my first choice of Aaron Eckhart seem a little bit too old. Patrick Wilson has played suburban secret-keeper before, and I think he has that quality of simmering unease.

And that leaves us with Jordan Baker. Baker’s one of my favorite characters ever, which is why I’m having such a hard time casting her in my head. Maybe Rooney Mara? She nailed the unavailable smart girl in The Social Network, but I’m leaning towards Evan Rachel Wood.

Okay, casting directors. Er, PopWatchers: Let’s hear it. Whom would you cast in the remaining roles in The Great Gatsby? What about Wolfsheim? Or the owl guy? And how do you feel about Mulligan as Daisy? Finally, can we really talk this much about The Great Gatsby without giving a shout-out to our high school English teachers? Nope! This one’s for you, Mr. Douglass!
