Animation has produced some of the most emotionally powerful and most visually extraordinary films in cinema history — movies that transcend their medium to become genuine masterpieces. Spirited Away is the highest-grossing film in Japanese history and won the Academy Award for Best Animated Feature in 2003 — a dreamlike masterpiece that works equally as a children's adventure and an adult meditation on identity and growing up. The Lion King defined a generation's childhood and contains some of the most emotionally devastating sequences in Disney history. Up delivered its famous opening montage — arguably the most affecting five minutes in animated cinema. Toy Story 3 made adults who grew up with the franchise weep in cinemas.
