Edward Woodward gives an electrifying performance as a reluctant professional killer working for British Intelligence. Callan became a national phenomenon in the late 1960s, making Woodward one of the highest profile actors on television and paving the way to his eventual career in America on shows like The Equalizer.

Created by James Mitchell (When the Boat Comes In) and exploring the dingy, twilight world of the professional spy, Callan was the antithesis of James Bond (back in the days of Connery and Moore) and presented, until that point, television's most realistic portrayal of government espionage.

This set contains the original Armchair Theatre pilot play, A Magnum for Schneider, along with all the remaining black and white episodes from series one and two – unseen in nearly forty years and available on any home viewing format for the first time.

Callan – The Monochrome Years will be released on UK DVD on 22nd February 2010 at the RRP of £29.99.
