Lieutenant Gene Hunt
Philip Glenister Manchester	Colm Meaney Los Angeles	Harvey Keitel New York
MOST NOTABLE: Keitel was the most famous actor to play in any of the series, although Philip Glenister of the Manchester version was fantastic and virtually steals the series.

Annie Norris

MOST NOTABLE: The Los Angeles Annie was the only one to have a weapon, the other two were basically police assistants.

Det. Ray Carling
Dean Andrews Manchester	Lenny Clarke Los Angeles	Michael Imperioli New York
MOST NOTABLE: Lenny Clarke was the only true comical character in any of the iterations, and had some pretty good one-liners.

Maya (Girlfriend)
Archie Panjabi Manchester	Stephanie Jacobsen Los Angeles	Lisa Bonet New York
