Green Shadows, White Whale is a 1992 novel by Ray Bradbury. It gives a fictionalized account of his journey to Ireland in 1953-1954 to write a screen adaptation of the novel Moby-Dick with director John Huston. Bradbury has said he wrote it after reading actress Katharine Hepburn's account of filming The African Queen with Huston in Africa. The title itself is a play on Peter Viertel's novel White Hunter, Black Heart, which is also about Huston.
Bradbury considers Green Shadows to be the culmination of thirty-five years of short stories, poems, and plays that were inspired by his stay in Ireland. As with most of his previous short-story collections, including The Illustrated Man and The Martian Chronicles, many of the short stories were originally published elsewhere and modified slightly for publication in the novel.
