Trivia: Both Frank Langella and Michael Sheen played their respective roles in the original Broadway production.
Trivia: The costume designer wanted Brad Pitt's suit to look really bad, but to her surprise, she discovered that no matter how cheap or tacky the suit was that he tried on was... he looked good in every single one. She eventually discovered the secret to finally making him look bad was to purposely put him in a suit that had the wrong measurements for his body, and give him gaudy wool ties.
Trivia: In the scene where Add gets to the beach and goes to the payphone, there's a "j.k. living" sticker on the payphone glass, which is the name of the production company that is owned by Mcconaughey. (Stands for Just Keep Living.)
Trivia: Jason's surname "Tripitikas" is a wry reference to the Chinese epic "Journey of the West", on which the film is partially based. In it, the Monkey King is freed from a stone prison by the monk Tripitika.
Trivia: Danny Wallace, on whose book the film was very-loosely based, appears in the Hen Night party scene near the end of the film, standing at the bar just behind Jim Carrey.
Trivia: Although the movie title is "27 Dresses", one of Jane's bridesmaid outfits is actually a man's black suit and tie (pant suit), and not a dress at all. This is shown at the end during Jane and Kevin's wedding. So really the movie should be called "26 Dresses and One Suit."
Trivia: At one point during the movie, Max visits a storage yard. The name of this yard is "Gognitti Storage". This is a reference to Vinnie Gognitti, who was an important character in the video game series.
Trivia: Despite her prominent billing, Dianne Wiest does not appear until an hour and twenty minutes into the film, and has less than ten minutes of screen time.
Trivia: While trying to locate Frank via gps, the techie is told to "hack into military satellites" to find him. There is a quick shot of a computer screen with code, and then it looks back at their faces. When paused on the code, you see the words "Command BitTorrent", which is a reference to BitTorrent, a program commonly used to download movies illegally off of the internet. Kind of ironic.

Trivia: Though Simone speaks English with an adopted French accent, Stana Katic actually can speak French, and it is one of five foreign languages in which she's fluent.
Trivia: Throughout the film, the five characters on the Mayan structure walk around in thin clothing day and night. In reality, it was quite chilly; the director and crew wore jackets to shield them from the cold.
Trivia: Julia Roberts, who plays Michael's mother, Lisa Taylor, is only nine years older than Ryan Reynolds.
Trivia: Hulk Hogan claimed he was offered the lead role in this film, which director Darren Aronofsky has disputed. Randy the Ram appears to be partially inspired by Hogan, given he was a megastar in the 80's, has bleach-blonde hair and a tanned skin complexion, and occasionally calls people "brother."
Trivia: Laura Harring, who plays Shannyn Sossamon's mother, is only 14 years older than Sossamon.
