Again the point is content, according to that link most epic films are filmed in 2.35 : 1 but that's not always true, in Bill and Ted's case I could give two squirts that a piece of the non-speaking morons of the side get chopped. THe content of Bill and Ted's doesn't warrant high-definition high-quality views like other movies. Movies like Star Wars EP2, LOTR, T2, that have lots of detail and great cinematic approach that are TRULY artistic deservers OAR treatment.
This has nothing to do with would you ruin the Mona Lisa or paychecks, I think that if every movie in 16x9 is bogus and you'd lose out on some good movies that way. However other movies don't matter I won't make a case for a 1960's Godzilla movie being cropped and zoomed SLIGHTLY for viewing on my HDTV. WHen the film quality is crap, what am I missing? A few plastic buildings? A piece of Gozilla's plastic tail? A few extra pieces of furniture accessories behind Adam Sandler?
