Kubrick's next movie was to going to be about Napoleon but he canceled it after another similar movie was released before his own. Kubrick worked very hard researching and learning about Napoleon and about the world at that time. Kubrick chose to make another movie set in that time that was titled "Barry Lyndon". The movie was based a book by William Makepeace Thackeray and was about an 18th-century gambler named Barry Lyndon. The movie was not as well liked as his previous movies but, like "2001: A Space Odyssey", it convinced people over time.
