I have seen the movies many times before, but I just picked up the Back to the Future 25th Anniversary Collection. It features all three films re-mastered (nothing added or removed, they just went back to the masters and improved the visual quality), along with tons of extras. Some of them are from the original DVD release, others are new and created specifically for this release. The collection also features digital copies of each movie so you can watch it on the go with your iPhone/iPod Touch/iPad, etc. I love all three movies, although I will admit that the first one is best. One of the facts that I didn't know before watching the extras, Sid Sheinberg (the head of Universal Studios at the time) wanted to call the movie "Spaceman from Pluto" and it took Steven Spielberg to convince him not to do it since everyone else liked the name "Back to the Future".
