'The Big Day' (1960) – Peter Graham Scott.

Made just before the dynamic, diametric shift of the more confrontational kitchen sink dramas like 'Poor Cow', and 'Darling', 'The Big Day' is a little more stolidly fashioned B-feature, while considerably less showy, Peter Graham Scott's compact, well acted drama about the the sly, internecine machinations of 3 disparate employees of a busy, mid-sized firm up for a directorship has much to recommend it to fans of vintage British melodrama. What might have been a somewhat glum, downbeat drama was vividly coloured by some robust acting from a capable cast with notably strong, well nuanced performances by future Hammer Horror scream queen Andree Melly as the immature, trampy, greatly manipulative teenage mistress Nina Wentworth, and terror titan Donald Pleasence is simply terrific as the melancholy, self-doubting accountant Victor Partridge whose somewhat sordid extra marital affair dramatically threatens both his mental equilibrium and his diminishing chances of promotion. 'The Big Day' is an engrossing study of toxic office politics, while not often mentioned, it remains a fascinating document, a fine, dramatically sound feature that proves once again what sublime acting range Harry H. Corbett revealed when playing straight, darker-edged roles, effortlessly oozing underhanded sleaze as the bone idol, money-grubbing schnook Harry Jackson.
