I think there were 4 or 5 deleted scenes. I only had the movie on DVD, but it got damaged last year. I hope the quality of the scenes are better on blu-ray and upscaling is possible.
I took a look at the deleted scenes on the Blu-ray disc, and the quality is really good. Upscaling might make the images a bit sharper, but I don’t think that upscaling is really necessary for those scenes, as the image quality isn’t bad.
