We know that Disney filmed additional footage specifically for the DVD/Blu-ray release of Tron: Legacy, but the nature and intent was in some doubt. It was first reported there might be a teaser trailer for Tron 3, but that appears untrue. (Another Tron sequel still hasn't been greenlit, mind you -- though it's close.) Some of this footage has surfaced online as a 10:27 clip titled "Tron: The Next Day." The focus is bridging the decades between the two Tron films, and the story ties heavily into the "Flynn Lives" viral campaign before Tron: Legacy's release. Garrett Hedlund, Bruce Boxleitner, and Dan Shor make appearances.The current over/under on this leaked clip is about four hours, and I'm betting on the under. So watch "Tron: The Next Day" while you still can after the jump.Via First Showing:-
