But the online retailer has already marked down a ton of products ahead of its made-up holiday, including a long list of 4K UHD Blu-ray movies. And, assuming you have the proper cables and setup, with 4K UHD Blu-rays, you get a picture quality that is better than compressed streaming content, too! Remember, you’ll need a UHD player to watch any of these movies. With that all out of the way, here are the UHD movies currently on sale on Amazon. Heads up that in the past, popular movies have sometimes sold out during these big UHD sales, so if something catches your eye, don’t wait too long to snag it.
