Ray Winstone ("Sexy Beast") has already been cast as Regan's sidekick 'George Carter'.
The original police drama, lensed entirely on film by Thames Television's Euston Films, focused on two members of the 'Flying Squad', a branch of the Metropolitan Police specializing in tackling armed robbery and violent crime in London.
The title derives from 'Sweeney Todd', which is Cockney rhyming slang for 'Flying Squad'.
The series previously spun-off the films "Sweeney!" /"Sweeney 2".
Director Nick Love and series creator Ian Kennedy Martin, wrote the new screenplay, aiming for a production start by the end of the year.
