Todd Phillips was having a hard time finding a blueish 1976 Lincoln for Huggy Bear. When he revealed this to Snoop Dogg, he was surprised to learn that Snoop actually owned a car of the right color and it's his car that appears in the movie.
When Vince Vaughn slaps Snoop Dogg during the golfing scene, it was actually unexpected the first time. Todd Phillips said, "Snoop went on with the scene and then when it ended he said, 'What the hell was that??'."
Originally, Todd Phillips wanted the knife-throwing scene to feature ninja stars instead. But the idea was scrapped when learning that any scene featuring ninja stars would automatically get an 18 Rating in the UK.
When filming the yacht scenes with Vince Vaughn, director Todd Phillips became very seasick and mentioned that he hated boats. When asked why he included one in his screenplay, he vowed never to write/shoot a scene on boats again.
One of the outtakes shown during the closing credits (the scene with the undressing cheerleader) has Starsky (Ben Stiller) blowing on Hutch's (Owen Wilson's) face to get his attention off the nude girl. This was a reference to a strip club scene from Starsky and Hutch (1975), used in the opening credits of that series.
Later on in the film, Ben Stiller and Owen Wilson are seen riding down the road, on chopper motorcycles, this scene pays homage, to the 1969 classic "Easy Rider". With Owen looking like Peter Fonda's character, and Ben looking like Dennis Hopper's character respectively.
About 10 1975-76 Ford Gran Torinos were totaled during production. Only two Torinos from the film were intact. One of them is a genuine 1976 Gran Torino with the Starsky and Hutch (1975) paint job, and the other was a base 1974 Torino which had been in storage. In reality, the 76 and 74 Torino which was used in the film was repainted with the white stripe resembling the one used on the TV show. All of the movie Torinos used 15-inch slot mag rims. They're not available new, so the rims (originally known as the Ansen Sprint, first introduced in 1963 and subsequently copied by several aftermarket wheel manufacturers e.g. E-T Wheels, Appliance, Cragar, Fenton, American Racing, U.S. Wheel) until the early 1980s) mostly came from swap meets, salvage yards, or eBay.
Heather tells Hutch that her sign is Gemini. Coincidentally, Brande Roderick, who plays Heather, is actually a Gemini; which means it's between May 21 and June 20. Roderick's birthday is June 13, 1974; which this movie was released three months before her 30th birthday.
28:43 Kenneth "Hutch" Hutchinson's (Owen Wilson) DOB is November 17, 1949 and attended Mt. Ridge Elementary school where he graduated in 1962. He graduated from high school in 1967. David Starsky's (Ben Stiller) DOB is June 10, 1950.
