This bit was at the end, but it might as well have been at the beginning. Or, really, just bannered across the bottom of the screen all the way through: "I am a performer. That is my life. That is what I am. That's it."

Let's face it, the rom-com has an image problem. Too often, this genre is tainted by either sugar-sweet sentimentality or crashing cliché, or both. Often, there’s something more than a little oppressive about the whole idea of romance, as if love’s natural idealism is too weak to withstand a cold dose of reality. But there are exceptions. And this show is one of them. It’s great to be able to welcome D C Jackson’s new play, which he calls a “non-rom-com”, and which arrives in London having first enjoyed a successful outing at the Edinburgh Festival in August.

Many theatregoers will be familiar with Clifford Odets’ Awake and Sing! which was given a recent revival both in the West End and on Broadway, or film-goers with his screenplay for Sweet Smell of Success (1957). Some will know his backstage drama The Country Girl (written in 1950) from the 1954 film version starring Grace Kelly, playing opposite Bing Crosby and William Holden, for which she won an Oscar.

Adultery has had a good press recently. Websites such as meet-to-cheat.com, illicitencounters.com and lovinglinks.co.uk have been in the news, and statistics suggest that more of us are being unfaithful than ever before. But although adultery is a staple of farce and mainstream drama, there are few plays that deal with the subject with quite the unsettling ambiguity and disturbing depth that characterise Martin Crimp’s modernistic play, first performed in 2000 and now beautifully revived by the up-and-coming Amelia Nicholson.

Either it’s a bizarre accident. Or there’s something in the water. Port Talbot, the unlovely steel town in Wales where smoke stacks belch fumes into the cloudy coastal sky, has been sending its sons to work in Hollywood for decades now. Richard Burton was the first to put his glowering blue eyes and golden larynx at the service of Tinseltown. Anthony Hopkins, for all his American passport, has never shed the native tinge from his accent. And in recent years there has been Michael Sheen (b. 1969).

You’ve heard of the Curse of Frankenstein. You know all about the Curse of Hello! But you may not be aware of the deadliest hex of them all. It goes by the name of the Curse of Cruise and, you just never know, it may be about to strike again. Film-goers have nothing to fear personally, not even if they find themselves watching potent soporifics like Interview with the Vampire or Eyes Wide Shut. No, the only way in which the Curse can possibly affect you is if you’re a young actress, and only then if you’ve been cast as Tom Cruise’s leading lady.

Five Easy Pieces is the nominal sibling to Easy Rider, which put Jack Nicholson a step from stardom in 1969. But Pieces, this 40th-anniversary reissue reminds you, was a very different film. The soundtrack is Patsy Cline, not Steppenwolf, and we first see Nicholson working in a hard hat, the music and garb of pro-‘Nam hippie-bashers in 1970. But the cultural action is mostly in Nicholson himself, and the simmering storm of dissatisfaction and high intelligence in his odd-angled, lean face, not often inclined here to split into that trademark super-smile.

He wasn't a jack of all trades, said his friend June Whitfield, "he was a master of all trades". The charge of "smarminess" dogged Bob Monkhouse throughout his career, but as this quietly penetrating documentary made clear, he was highly intelligent, multi-talented and had a lot of layers he kept to himself. Actor, scriptwriter, singer, novelist (though they didn't really mention that part), stand-up comic, cartoonist, radio star, gameshow host and posthumous campaigner against the prostate cancer that killed him - the only thing Monkhouse couldn't manage too successfully was his work-life balance.

Julianne Moore (b. 1960) is a true rarity. It’s not just that her hair flames like no other star since Katharine Hepburn. Or that alone of her generation she seems impervious to middle age’s indignities. There’s something else. Having worked with dinosaurs in The Lost World and a cannibal in Hannibal, she is mainstream enough to be considered a genuine leading lady. But much of her most eye-catching work, often written for her by indie directors like Todd Haynes and Paul Thomas Anderson, is fiercely extreme in spirit.
