The Marked One is a 1963 British second feature[1] crime film directed by Francis Searle and starring William Lucas, Zena Walker and Patrick Jordan.

Truck driver Don Mason is an ex-con who served time for involvement in a forgery racket, and is now trying to go straight.

A blackmailer demands the plates used in the forgery, threatening Mason's wife and kidnapping their child.

[1] Monthly Film Bulletin said "Spot-the-blackmailer crime thriller, quite neatly built but sleazy and slackly motivated (why is everyone so crassly opposed to going to the police?).

The direction is nondescript; William Lucas, Zena Walker and Brian Nissen act well despite stereotyped roles.
