Sorry for the late notice, I only learned about it today. I was able to check it out since I work in downtown LA a few blocks from LA Live.
There is a (very) limited time Dark Knight Legend exhibit at LA Live that is promoting the release of the latest Christopher Nolan Batman movie on DVD/Blu Ray. There are costumes, props, models and miniatures from the Nolan Batman flicks, as well as a couple of the Tumblers. But, that's not all. The Keaton, Clooney and Kilmer Tim Burton Batmobiles, which are way cooler looking, are also on display. And, the coolest of all, the old tv Batmobile is also there! The exhibit only goes through Friday, Dec. 14th, for those in the LA area who may be interested in checking it out.
