Drew Goddard wrote the screenplays for Ridley Scott’s 2015 film *The Martian***and Phil Lord and Christopher Miller’s *Project Hail Mary*, both based on Andy Weir novels about astronauts using all their ingenuity to survive in space. Goddard captures Weir’s mix of complex science and goofy humor in highly faithful and captivating adaptations, but he also cuts one of Weir’s weirdest recurring gags from both books: cannibalism humor.
