Christopher Nolan's adaptation of 'The Odyssey' is reportedly his most epic movie yet, with some outlets suggesting it could be his biggest blockbuster. The film has already generated controversy and broken a box office record, although its long-term impact is uncertain. The movie features notable performances, including one from Samantha Morton that has drawn comparisons to Heath Ledger's Joker, and its production is notable for being Nolan's most expensive in 14 years.
