Website Blu-ray.com review of the Blu-ray and the reviewer says it's from a older master but it looks good. Mine is in the mail and should get it soon. By the way the lack of extras is a bummer.
Have the Blu-ray and did a quick comparison to the dvd and the only big difference is a sharper looking image on the Blu-ray. The color is the same on both but what a bummer that the trailer is on the dvd but not on the Blu-ray and to me Paramount should have done better with that and some extras.
