Jim Cunningham depicts drugs, alcohol, and premarital sex as “instruments of fear.” In the movie, Donnie smokes a cigarette, drinks alcohol, and engages in premarital sex. The climax of the movie occurs after he surrenders to all three temptations.
There are many comic book references that show up through the film. Gretchen comments on Donnie’s name as sounding like a superhero, to which he replies “What makes you think I’m not?” Many characters have alliterative names (Donnie Darko, Cherita Chen, Frankie Feedler, Daye Dennis, Joanie James, Sean Smith, Donnie Dickson) like many comic book heroes (Peter Parker, Bruce Banner, Susan Storm etc.). Also, it is believed that Donnie is a superhero, as he has powers and he uses them to save others.
The words “Cellar Door” are written on the chalkboard in Karen Pommeroy’s classroom. When Donnie asks about their meaning, she replies that “This famous linguist once said that of all the phrases in the English language, of all the endless combinations of words in all of history, that Cellar Door is the most beautiful.” In the director’s commentary Richard Kelly mistakenly attributes the phrase to Edgar Allan Poe, but it was actually J.R.R. Tolkien who, in his 1955 essay “English and Welsh”, said that “Most English-speaking people … will admit that cellar door is ‘beautiful’, especially if dissociated from its sense (and from its spelling). More beautiful than, say, sky, and far more beautiful than beautiful.”
When casting for the role of Donnie’s sister, it came to Richard Kelly’s attention that Maggie Gyllenhaal (who had few film credits at the time) would be available for the shoot. The agent who proposed her casting reminded Kelly of her scene in Cecil B. DeMented, where she drank urine. Though Kelly was slightly hesitant towards the idea, he did like the way she drank urine - and knew he wouldn’t have to work hard at creating a sibling rivalry between her and her brother, star Jake Gyllenhaal.
The song that plays as Donnie is riding his bike home in the theatrical version is “The Killing Moon” by Echo & The Bunnymen. As Gretchen waits for the school bus, a Volkswagen Rabbit vehicle quickly passes in front of her. When Elizabeth Darko is sleeping on the recliner, there is a stuffed rabbit next to her. As Donnie reaches for the car keys, there is a Polaroid picture of him and his sister in Halloween costumes on the desk. Donnie is dressed as a rabbit. When Donnie is talking to his sister after his mom leaves near the end, a “jack o lantern” bunny is seen on the table. Frank, the rabbit, often appears near a water source (sprinklers, water main, faucet).
The movie takes place in 1988. Frank tells Donnie the world will end in 28 days, 06 hours, 42 minutes, and 12 seconds. If you add these numbers, the sum is 88. When Samantha asks when she can have kids, Donnie says: “Not until 8th grade.” Donnie mentions to his therapist that his dog Callie died when he was eight. (He is later seen holding a stuffed toy dog in her office.) Donnie jokes about the Back to the Future DeLorean which had a speed of 88 MPH. According to the television reporter, the fire at Jim Cunningham’s house was extinguished “sometime after 8:00 last night.” The red-eye flight that almost crashes is Flight 2806 which boards at Gate 42 at 12 AM. The climax of Donnie Darko occurs one week before the 1988 US presidential election, when George Bush won on November 8, 1988. The movie was shot in 28 days. There are 28 scenes in the director’s cut of this film.
The scene where Donnie corrects Gretchen was improvised because the actress could not say the name Prof. Kenneth Monnitoff, correctly.
In the movie theater scene, Richard Kelly originally intended to have Donnie and Gretchen going to see C.H.U.D.. However, there were problems with finding out who owned the rights to the movie. Finally, Sam Raimi came to the rescue by allowing Kelly to use and distort footage from The Evil Dead, free of charge.
During conversations about sex with his therapist, the script had Donnie’s fantasies be about Alyssa Milano. This had to be changed to Christina Applegate due to legal reasons.
Richard Kelly said that the movie had a very difficult time finding a US distributor. Since the film embodied myriad genres and tones, distributors were confused by the movie’s message, and how to market it. Additionally, Kelly also claims that “Darko” was very close to premiering on the Starz network until Newmarket Films picked up the film for theatrical distribution.
