The 4K version of this movie has some of the best scenes that are clearer and more vibrant than the regular blu-ray. But there are some scenes that are about the same because they were shot with a different camera so you can only work with what you have! Other than that, Great performances from John Belushi (who has sadly passed away) and Dan Ackroyd, great music, tons of cameos from well known musicians and actors, laugh out loud moments are plentiful! Plus it's a great story and well written script! Greatest movie ever!! Must see! Very funny classic movie!
