NEVER BEFORE SEEN: The Entire Biff Tannen Museum Video from Back to the Future II

 From BTTF.com

“BTTF.com has recently uncovered a copy of the complete video monitor footage from the ‘Biff Tannen Museum’ scene in Back to the Future™ Part II which Marty McFly (Michael J. Fox) watches at the museum’s entrance while he’s looking for answers about his father’s demise.

The 3½ minute segment was digitized from an old VHS tape which had been saved by a Back to the Future fan with family connections to the film production at the time the sequels were shot in 1989-1990. To date, the following clip is not available on any other commercial collection, including the recently released 25th Anniversary Trilogy Blu-ray Disc and DVD boxed sets.
