The Grass Is Greener is a 1960 British romantic comedy film starring Cary Grant, Deborah Kerr, Robert Mitchum, and Jean Simmons.

It was directed by Stanley Donen, with a screenplay adapted by Hugh Williams and Margaret Vyner from the play of the same name they had written and found success with in London's West End.

Like many other such estates, they have opened up their house for guided tours for the public at two shillings and sixpence per person, but are making a comfortable profit on it, growing mushrooms for market, and other minor estate-related enterprizes.

That evening, Hilary makes an appointment with her hairdresser in London for early next day, explaining to Victor that she will have to stay overnight with their friend, the single Hattie Durant.

Victor phones Charles' hotel and invites him to visit; he accepts, against Hilary’s wishes, and even offers to give her a lift back from London.

When the women learn of the duel and Victor's wound, Hilary cannot bring herself to leave her loving husband for Delacro, who drives off with Hattie in her stead.

It was originally intended by director Stanley Donen that Grant would play the part of Delacro, the American tourist, while Harrison and Kendall were respectively cast as "Victor Rhyall" and "Hattie".
