Much-loved character actors David Field and Dan Wyllie play the two impatient henchmen holed up in a dark warehouse waiting for a delivery, oblivious to the threat lurking outside.
The bickering bad guys waiting for a drug deal are played by Jesse Plemons (aka Landry Clarke from Friday Night Lights) and the hilarious Jason Mantzoukas (aka the unhinged Adrian Pimento in Brooklyn Nine-Nine).
Genevieve Morris plays tough-talking Carol, the seen-it-all-before dispatch leader. Harriet Dyer plays cop April, who's demoted to the desk after an unfortunate taser incident.
Playing similar characters, the US version stars Amy Sedaris as Janice and Sunita Mani as Fatima.

Tim Meadows, known for his performances in the films Mean Girls and Walk Hard: The Dewey Cox Story, takes on the role of hapless detective Judd Tolbeck. Meanwhile, Aussie actor Patrick Brammall plays… wait a minute! He plays the very same character. But American. And with a slightly different name.
