Peter Bos' character, Henk Berkhout, works as a gardener in the Vondelpark, Amsterdam, where he drives around in a tricycle Piaggio Ape pickup.
The police cars in this film were provided by a car rental company in Amsterdam and outfitted with light bars, a siren and police stickers by the Amsterdam police department.
Some sets were built inside the then defunct Amsterdam innercity hospital "Binnengasthuis".
