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 and exploring the dingy, twilight world of the professional spy, Callan was the antithesis of the James Bond films and presented televisions most realistic portrayal, until that point, of government espionage.

The Worst Soldier I Ever Saw only exists as an unedited recording block and has been re-edited into its proper transmission format for this release.
