I know watching at a drive-in is more traditional but Graffiti on blu ray will have the best picture you can get for viewing. Im about to go out and get my copy. I'm anxious to view the new extras too.
extras on the Blu ray: U-Control: o Video commentary with director George Lucas o The Music of American Graffiti* The Making of American Graffiti * Screen Tests * Theatrical Trailer also - for those that are really into the movie - be sure to look at the sunset in this version at the beginning of the movie - compare it to the OLD version - yes - Lucas changed the sunset via CGI the guy cant leave anything alone
