Hot Fuzz is the second film in the Blood and Ice Cream Trilogy and features the blue Classico flavour of Cornetto.
When Danny is looking at DVDs at Somerfield, a Shaun of the Dead DVD can be seen in the bin.
In the DVD commentary featuring Simon Pegg & Edgar Wright, they mention that the "Judge Judy & Executioner" joke was previously used in an episode of The Simpsons unbeknown-est to them.
Robert Rodriguez scored a few sections of the film. Direct Edgar Wright points out on the DVD commentary that he agreed to contribute music after only seeing a few scenes from the film out of context.
Nicholas Angel originally had a love interest written into the film. It was taken out, though, and a lot of the lines were cycled over to Nick Frost's character.
Somerfield is a real UK supermarket chain, and all of the exterior scenes were shot at one of their stores. Edgar Wright chose to use it as he worked there as a shelf-stacker as a teenager, and in a nod to this, he makes a blink-and-miss-it cameo as a shelf-stacker in the Somerfield store.
The picture of a young Danny is a real picture of Nick Frost as a child.
Many of the characters have names with hidden meanings. For example, P Shooter (Philip Shooter) and Eaves Dropper (Eve Draper).
Nicholas Angels masked ex-girlfriend is played by Cate Blanchett.
Danny's DVD collection is made up of the combined collections of Edgar Wright, his brother Oscar Wright and his friend Joe Cornish.
Hot Fuzz is filmed in the city of Wells, director Edgar Wright's home town.
The man dressed as Santa Clause who stabs Nicholas Angel is Peter Jackson.
Sanford, the fictional setting of the film, is the name of the town used in police training role plays.
