Looks like a great collection, lack of The Producers notwithstanding, but under the product details, the aspect ratio is listed as 1.33(or 4:3, aka "standard" television ratio, as opposed to widescreen). I'd guess typo, as it seems unlikely that they'd crop films on blu-ray to fit a standard definition television, but I'd rather not spend the money and find out the hard way. Can anyone who's bought the collection sound off on this?
As JMM says, all movies are widescreen, with aspect ratios between 1.85:1 and 2.40:1. See the images I uploaded for the Mel Brooks Collection that is like this set except it has the hardback book (each image includes aspect ratio, audio, and subtitle info for each movie):
Still going to buy this Deal of the Day offer since the price is so good... but it still makes me wonder about the aspect ratio. At this price I can use the discs as coasters if the movies are not widescreen.
