In the scene where Wallace fetches the giant rabbit after it has come off the van, Gromit turns on the radio, and we hear a song called "Bright Eyes" from the film 'Watership Down' a film about rabbits.

When Gromit's waiting for Wallace to retrieve the giant fake rabbit from where it hit the tunnel wall, we see a fruit and veg shop called "Harvey's". A reference to a classic Jimmy Stewart film from 1950 called "Harvey", where he plays a man who has an invisible 6 foot tall rabbit for a friend.

In the scene were Gromit is taking care of his melon he looks at a calendar and the date circled for the festival is September 17, which was also the day the British launched operation Market Garden. It's the perfect date for a vegetable festival.

Just after Wallace and Gromit have gone under the bridge (losing the female decoy in the process) and Gromit is on his own in the van, look at the shop just beside Harvey's Fruit and Veg Store. It is a barber shop called 'A Close Shave' an homage to an earlier adventure.

Everything Hutch says was spoken by Wallace either earlier in the film, or in one of the three Wallace and Gromit shorts.

The scene with Gromit being pulled through the tunnel in the car by the were-rabbit is a take-off of the original "The Italian Job" chase through the sewers.
