Whether this is the height of nostalgia culture, the result of commendable efforts in media preservation, or just a big coincidence, there are a lot of cool films being remastered in 4K. Last month, it was reported that Mamoru Oshii's Ghost in the Shell 2: Innocence would be back in theaters in 4K, and now Oshii's back again, this time supervising a remaster of his cult classic, Angel's Egg.
