Only Two Can Play is a 1962 British comedy film starring Peter Sellers, based on the 1955 novel That Uncertain Feeling by Kingsley Amis. Sidney Gilliat directed the film from a screenplay by Bryan Forbes. The film is set in the fictional South Wales town of Aberdarcy, and largely filmed in and around Swansea, Amis's stated model for Aberdarcy. It was the first comedy to receive an X certificate in the United Kingdom. Plot John Lewis (Sellers) is a poorly paid and professionally frustrated librarian and occasional drama critic, whose affections fluctuate between glamorous Liz (Mai Zetterling), and his long-suffering wife Jean (Virginia Maskell). When a better paid job becomes vacant, Lewis is reluctant to apply, but is persuaded to do so by Jean. Then, he meets the obviously attractive Elizabeth Gruffydd-Williams (Liz), a designer with the local amdram company and wife of a local councillor. Liz offers to intercede with her husband to help in getting Lewis the job, and makes it clear that she is attracted to him. Lewis is easily seduced into an affair, although it remains unconsummated. Having been persuaded by Liz to leave the theatre's new production early one evening for an assignation, Lewis submits a bogus review to the local newspaper, but learns the next morning that the theatre burned down shortly after the play commenced. Jean thus learns of the affair and retaliates by encouraging her old flame Gareth Probert (Richard Attenborough), a self-important literary character and dramatist (who wrote the ill-fated play). Lewis also loses the friendship of his colleague and best friend, Ieuan Jenkins (Kenneth Griffith), who had a role in the play. When Lewis is offered the better paid job, he realises that Liz will now use and control him if he lets her. Finally realising the price he has paid, he breaks off the affair and takes a job as a mobile librarian, in the hope that this will keep him away from predatory women. Jean is not so sure that he can resist them, and tags along to keep an eye on him.
