Loser Takes All is a 1956 British comedy film directed by Ken Annakin, starring Glynis Johns, Rossano Brazzi and Robert Morley.

His boss, Dreuther, the powerful director and major shareholder of his company, arranges for Bertrand and his fiancée, Cary, to marry and honeymoon in Monte Carlo.

However Sir Arthur Jarratt, then head of British Lion, refused to finance with either actor, or another suggestion, David Niven as Bertrand.He did allow Rossano Brazzini who Annakin felt was "completely wrong for the character".

It turned out that although the book was brilliant and funny, cinema audiences had no sympathy for a girl who felt deserted by her husband during the few days he was amassing millions.

"[4]: 79 The Monthly Film Bulletin wrote: "The main interest of Loser Takes All as a book lay in the author's change of style; a kind of modern fairy story seen through a well-seasoned, slightly jaundiced eye, the narrative revealed Greene in a fairly light and capricious mood.

The screen version (scripted by Greene himself) seems less immediately personal; what was acceptable as a minor literary work is here given lavish production treatment which only serves to exaggerate its lack of comedy substance.

"[6] Kine Weekly wrote: "Glynis Johns and Rossano Brazzi handle the extravagant happenings with disarming inconsequentiality and their engaging teamwork performed against authentic and picturesque backgrounds weaves the wild improbabilities into glorious escapist fare.

Ken Annakin's breezy direction keeps the action moving and the highgrade color lensing by George Perinal gives a glossy finish to this British 'Scoper.

The casting of Glynis Johns and Rossano Brazzi as a newlywed couple honeymooning in Monte Carlo at the invitation of a vaguely characterised and only intermittently seen Robert Morley is a pairing so unlikely as to sink the enterprise on its own.
