Angel’s Egg (1985) IMDb
An almost deserted world in cold, dark blues. A young girl protects a large egg. A man with a cross-shaped object finds her and starts to follow her around, telling her that she cannot find out what an egg contains without breaking it. He later quotes The Bible (ca. 110 CE) at length and shows bandaged hands. Nearly petrified people throw harpoons at enormous shadows of fish that might not really be there.
Surrealist myth, progressive animation. Oshii. 1985 indeed; Japan’s bubble economy was nearing its peak, loans were cheap, so investors were plentiful and anime got mature and experimental in films like this one. It looks great and some of the symbolism is nice.
