Gone Girl vaults to the top of David Fincher’s box-office chart with the best opening weekend of his career. $38 million; that’s 4.5 million tickets. Panic Room made $30 million selling 5.1 million tickets 12 years ago (in 2002, when Ellar Coltrane was 6 years old). In 2010, The Social Network had a $22 million debut weekend and went on to earn $96 million. Last week 20th Century Fox was cautiously estimating Gone Girl would clock in with $22-25 million. It will be interesting to take a look at the demographic breakdown of Gone Girl ticket-buyers. We’ll add those stats as soon as I find them.
