The description sounds good to me.
If I'm not mistaken, zoot suits had broad, padded shoulders and were born out of the 1940's, not the 1980's. What era did the Joker originate? The 1940s. I dig the description. Bleached clown skin? Check. Crazy suit and style? Check. By the sound of it, they're moving away from the emo, punk, anarchist Joker from 2008 and going back to something classic. Nothing in that description worries me if it's legit, sounds cool as hell.
I've always wanted to see Hugo Strange in a film too, so that's great news. He was the very first Batman villain from the famous rogues gallery, can't wait to see how they handle him.
