Two seconds. Three at a push.
That's about as much new material you'll find in the latest Star Wars: The Force Awakens TV trailer that the franchise's South Korean YouTube channel just dropped.
The opening shot is perhaps most significant for fans of "scan every frame for new details and spoilers", showing what appears to be the remains of the fallen Empire forces amassing on a frozen planet. Otherwise, it's roughly 15 seconds of bad guys followed by 15 seconds of good guys.
Heck, it's an excuse to get excited about Star Wars again. So go nuts.
