During filming, Jim Carrey stayed the night at the Stanley Hotel and requested to stay in the infamous room 217 (see Stephen King's: The Shining). According to the tour guide at the hotel, about three hours after Carrey went to sleep, he came running out of the room and left the hotel. To this day, he vows to never go back and won't tell anybody why. It is said to be because he saw the ghost of his grand dad.
Jim Carrey was initially offered $700,000 to appear in the film. However, the offer went in the same week when Ace Ventura: Pet Detective (1994) opened at number 1 in the US box office, so by the time Carrey's agents had renegotiated with the film's producers, his salary had upped itself to $7 million, almost half the film's budget.
According to the Farrelly brothers, Jeff Daniels wasn't wanted for the film, but Jim Carrey wanted him in it. In order to ensure a no from him, they offered Daniels $50,000 for the role. He accepted without any hesitation nor did he attempt to negotiate.
When the film went to the top of the US box office, it gave Jim Carrey the distinction of being the first actor to have three films go straight to number one in one year (those films being this, The Mask (1994), and Ace Ventura: Pet Detective (1994)).
Although the ultimate travel goal was to reach Aspen Colorado, the actual town wanted too much money for film rights so many scenes were shot in nearby Breckenridge. The script however, was untouched. Certain shots were filmed in Estes Park, Colorado at The Stanley Hotel.
The restaurant scene (with Seabass) was filmed in Ft. Morgan, Colorado. However filmmakers originally wanted to film this scene at a restaurant in Wiggins (about 15 miles west of Ft. Morgan) but after viewing the script the owner refused.
During the men's room stall scene, when Lloyd checks the time, the close-up of his wristwatch reveals it to be a "Casino Alarm Chronograph", suggesting it is a fake of the already, very inexpensive brand, Casio; it also lacks any of the dials found on a real chronographic timepiece, along with the 5, 6, and 7.
Bennett Yellin's initial draft of the script was apparently so disjointed that it had gained a negative reputation among film investors. After the script was re-written, it was pitched to producers under the fake title "A Power Tool Is Not a Toy", in order to get them to even read it.
Among the many writings on the gas station bathroom stall are: "Why are you looking up here when the joke is in your hand?", "Bye Bye William Frawley", "NAMBLA Rules", and "Why the hell is everyone so goddamned angry?".
The hotel, bar and Lamborghini scenes were shot at The Historical Stanley Hotel in Estes Park CO. The "We landed on the moon" photo in the bar remains on the wall. The Stanley was the inspiration for Steven King's The Shining.
This is the second movie released in the same year in which Karen Duffy plays a character named Shay. She also played a character named Shay Stanley in Blank Check (1994). It was also the second movie released in the same year in which Jeff Daniels played a character named Harry. He also played Det. Harry Temple in Speed (1994).
An entire subplot was filmed involving Mary's kidnapped husband Bobby being kept in a wooden shipping crate, but was ultimately discarded. The brief scene where Nicholas and Shay discuss the snow owl incident had originally led into a scene where Bobby manages to escape while still inside the crate.
When Harry and Lloyd are trying to remember or guess Mary's last name while in Aspen, Lloyd can read the briefcase name as Samsonite but when he reads the newspaper after crying over a commercial he can barely read the newspaper. He had trouble with the words, the, annual and international.
