Trivia: When Mongo falls into the moat, The Gingerbread Man jumps in after him screaming "He needs me." Elliot yells the exact same thing when E.T. is taken away, and upon submerging in the moat, Mongo says "Be good," just like E.T. in "ET: The Extra-Terrestrial" (1982).
Trivia: When the police are chasing Shrek, Donkey and Puss in Boots, the radio dispatcher says "We are in a high speed pursuit with a White Bronco....." This is a reference to the infamous O.J. Simpson car chase in 1994.

Trivia: During the first bedroom scene with the King and Queen, the king goes to stand on the balcony where he meets the Fairy Godmother. The queen asks where he is going, and the king replies: "Bit of trouble from the old crusade wound, gonna go outside and walk it off" while holding his knee. This is a reference to John Cleese's (King) character in "Fawlty Towers" (1975), Basil Fawlty, who has a war wound in the exact same place, and also uses it as an excuse to get out of a situation.
Trivia: The gate to Far Far Away is the famous Bronson Gate at Paramount Pictures Studio in Culver City, California.
Trivia: In the scene in the Fairy Godmother's workshop, there are two pictures placed next to each other.

Trivia: At the very beginning of the Honeymoon montage, we see Shrek looking directly into the camera and moving it around to get a good shot of him and Fiona in front of the house. The is exactly the same as the opening credits for the late 1980s TV program "The Wonder Years" (1987).
