There were talks going on for years trying to get an American remake of Battle Royale off the ground. However between The Hunger Games beating them to the screens while already being a massive BR ripoff and largely indicative of how uninspired an American BR remake would be, and the fact that Americans can watch their school kids gunning each other down on a TV show called "the news" every couple of months already, plans to remake it have been shelved.
The sequel was bad enough to BR's legacy, we don't need the Americans whitewashing it to tarnish it even further.
