We're told the final big-screen trailer for the new live-action Transformers movie is coming early this afternoon. We don't have that for you yet, but we're assuming it'll get leaked out early. For the time being, here's the 30-second clip that aired last night on American Idol. Other than a couple of seconds of new fleshy video, there's also the additional shots of everyone's favorite evil robot who transforms into a jet — Starscream. Yup, eat it up quickly kiddies, you'll want to leave some time to digest before the main course later this afternoon.
