Trivia: Rhiannon Leigh Wryn, who played Emma, was also the voice of Mimzy; her voice was digitally altered and added in post-production.
Trivia: The fact that the character of Charlie is shown playing the video game "Shadow of the Colossus" was an intentional choice by the filmmakers, who had to get permission from the game's director to include it into the film. It was decided Charlie would play this game based on the symbolism of the gameplay (which involves the destruction of giant "colossi", whose deaths are somewhat similar to the collapse of the twin towers during 9/11, and the fact that the main character is trying to bring someone back from the dead), and how it related to his character .
Trivia: The actress who plays Debbie is Leslie Mann, and she is the real-life wife of writer/director Judd Apatow. And the two girls who play Debbie's daughters are their daughters in real life. This was done on Apatow's part to make the on-screen family seem more like a real family.
Trivia: In the DVD commentary, Director Joe Wright reveals a lucky fluke that got caught on camera during the scene just before Robbie (James McAvoy) discovers the school girls massacre. At the point where he removes his helmet, the weather was cloudy. As he looks up the sky, the sun started shining, and then got cloudy again the moment he put his head down.
Trivia: Tilda Swinton won the Academy Award for Best Supporting Actress for her role as Karen Crowder, even though she's only in the film for 18 minutes.
Trivia: During the courtroom sequence, the judge is played by actress Judith Roberts, and her character's name is "Judge Shaw." Her appearance and name is a direct reference to director James Wan's previous film "Dead Silence", where Roberts had played a character named "Mary Shaw."
Trivia: Early on in the movie, when Ian Curtis (played by Sam Riley) enters his parents living room, there is a picture of the real Ian Curtis as a boy on the mantelpiece.
Trivia: Dianne Wiest (born 1948), who played Dan Burns' mother, Nora, is only fourteen years older than Steve Carell (born 1962).
Trivia: When Abe Dale comes into a room (possibly a church?) where the children's choir is singing, the song is Rush's Spirit Of Radio.
Trivia: Angelina Jolie was pregnant with her daughter Shiloh when she portrayed Mariane Pearl, who was pregnant with her son Adam during the events of the movie.
Trivia: Kate Nelligan plays Sandra Bullock's mother in the movie, even though in real life she's only 14 years older than Bullock.
Suggested correction: Google her age and you will see this is incorrect.
Or you could have just submitted a word change pointing out the age difference is 14 years rather than 13. Hardly makes the entry wholly incorrect.
Trivia: Chris Pratt had planned to audition for the role of Chris Pratt, thinking he would land the role simply for having the same name as the character. However, he postponed the audition to go on a fishing trip, and by the time he had returned, Joseph Gordon-Levitt had been cast in the role.
Trivia: The prop department had some fun during the making of the movie; you can see a lot of names of miscellaneous crew slipped in a few spots. There are boxes with case files scattered around the district attorney's offices; the ones behind Willy in his own office (People vs. Bonaventura - Tony Bonaventura being the property master, People vs. Morgenthau - Kramer Morgenthau being the director of photography) get quite a bit of screen time, but there are several others all over the office space, all carrying the name of a crew member. For instance, in a brief sequence when a dejected Willy walks up to Mona's desk to ask for her help before the third act, you can see unique ones. There's also a listing board with judges during the arraignment, and one with doctors when Willy is stopped by the hospital security; both of them are filled with names of production crew members.
