Now this is what we call a trailer! Another preview for Eclipse  made its debut on the Friday taping of Oprah just a few minutes ago, and boy, is it action-packed. We've already gotten a taste of the love triangle  we all know is coming, but now here's a much better look at the action scenes we've been promised. There's plenty of the Cullens this time around — something we thought was missing from the first trailer  — and the wolf pack makes an appearance too. Plus, the vampire battle scenes look awesome, right up to a very creepy look at Victoria's newborn army emerging from a lake. Oprah also revealed that Robert Pattinson , Kristen Stewart , and Taylor Lautner  will all be on her show May 13, which happens to also be Mr. Pattinson's birthday. Our excitement just shot up about 20 levels — check it out now!
