Trivia / Inferno (2013)

• Box Office Bomb: Budget, $75 million. Box office, $34,343,574 (domestic), $220,021,259 (worldwide).
• Franchise Killer: After two successful films, this one's failure spelled the end of the film side of the Robert Langdon series of books; the creators were upfront about the fact that they only did the films for the money, and this one's failure killed any incentive to go on.
• Sequel Gap: The film was released 7 years after Angels & Demons.
• Working Title: The film was codenamed "Headache" during production, most likely as a reference to the head injury Langdon suffers at the start.
