Criterion has unveiled its first 4K Ultra HD Blu-ray releases with a six-film slate that includes Citizen Kane, Menace II Society, The Piano, Mulholland Dr., The Red Shoes, and A Hard Day’s Night.

I hope that you have some spare room on your shelves for DVDs and Blu-rays, because Criterion is hosting another one of its rare flash sales, marking down everything in its catalog by 50%.
