It has to be partial, because out of the 10 opera productions from the iconoclastic French actor-director, who died yesterday of lung cancer at the age of 68, I’ve seen but two, on screen only – but a big two at that – and only three of his 11 films. Yet they all had a tremendous impact, one way or another.

David Frost, who has died at the age of 74, was a character. The obituaries will tour the entirety of his career as swinging young presenter of TW3, as the first transatlantic celebrity of the gogglebox who gave his name to a sugary brand of Kelloggs cereal, and as a lifelong thorn in the side of Peter Cook. Then there was Through the Keyhole and the TV-am cataclysm later followed by his Sunday morning resurrection on the BBC. Above all, though, it falls to vanishingly few interviewers to see themselves fictionalised as a character onstage.

Hysteria is back. Terry Johnson’s comedy was written for the Royal Court in 1993, and for its 20th anniversary it is being revived at Hampstead Theatre. It is a homecoming in a sense: the play is set in the Hampstead home of Sigmund Freud, where he receives unexpected visits from Salvador Dalí and a young woman who cannot keep her clothes on. Freud will be played by Antony Sher.

The Machine by Matt Charman is about the famous chess match between the then world champion Garry Kasparov and the chess computer, Deep Blue, which took place in New York City in 1997. The match captured the imagination of the general public at the time as perhaps no other chess match has before or since. Kasparov's face was hanging in Times Square and the New York Stock Exchange had the match on its screens.

Even now, as Edward Snowden floats in the diplomatic neverwhere of Sheremetyevo airport, someone somewhere is plotting the movie. Currently the story of the man who blew the whistle on the National Security Agency looks like it could still play out as farce, but it may yet turn to tragedy.

A few days ago I found myself sat in a Finsbury Park pub talking to a man who dismantled bombs for a living, who had completed two tours in Afghanistan fighting the unending war against Improvised Explosive Devices, and I will admit to being more than just a little nervous. You see, he had just read the script of my play Casualties.

Very few young people know her name today, but Dorothy Squires was the singing sensation of the Fifties and Sixties, and even 30 years ago this talented but difficult star was a regular feature of the headlines thanks to offstage dramas and scandals. But who was the real Dorothy Squires? I first remember meeting Dorothy Squires, as she renamed herself, when I was only three years old. My father, Bert Cecil, a pianist, had befriended her when, aged 15, she had gone to London armed with nothing more than hope and a train ticket.

If this native New Yorker were in a relationship with the city of London, our Facebook status would read: “It’s complicated.” We’ve been through hell together. London is one of my favourite cities. I blissfully cross the pond several times a year to teach and to see my mates. But, this fabulous city also bestowed on me the worst reviews I’ve ever gotten in my life. So, why the heck am I coming back to do yet a show about the very show that shattered my dreams? Insane!

In recent years theatre has sought assistance from a pair of popular art forms. Shows based either on movies, or on pop groups’ back catalogues, have become mainstays of the theatrical economy. So the latest musical to open in the West End has the whiff of  boardroom cynicism. What happens when you randomly select a famous film and an iconic songbook, yoke them together and shove them out in front of the footlights?

Knock knock. Who's there? Eamonn. Eamonn who? Eamonn Etonian. There's an Eamonn at No 10, an Eamonn is Mayor of London, an Eamonn is even Archbishop of Canterbury. Oh, and Eamonns are third and - for three more months - fourth in line to the throne. Recently Eton has started to dominate British film, television and theatre. In 2012 one Eamonn won an Emmy, another was given a Bafta and a third played a Shakespearean king on the BBC.
