Trivia: Even though Angelina Jolie plays Colin Farrell's mother in the movie, she is only a year older than Farrell.
Trivia: Monroe Cole states that people will be calling him Mr. President for the rest of his life. While it is true people do tend to call former presidents by that title (thus not a movie mistake), as a point of trivia; is it incorrect to address a former president as "Mr. President" or "former president (surname)." While Cole doesn't have to worry about his ex-wife taking his title, leaving office will do that. It's the media that perpetuates this presidential title error.
Trivia: Although they play father and daughter in this film, John Turturro (born 1957) is only seven years older than Monica Bellucci (born 1964).
Trivia: In the English dub of the film, Anna Paquin voices Ray Steam, Alfred Molina voices Edward (Ray's father) and Patrick Stewart voices Lloyd (Ray's grandfather). The three also share another connection in real-life. Paquin and Stewart co-starred in all three "X-Men" films, which were created by Marvel, and Molina starred in another popular Marvel comic-turned-film, when he appeared as the villain in "Spider-Man 2."
