Two cult classics from the silver screen are set to be reincarnated at London’s oldest pub theatre.

The King’s Head Theatre in Upper Street has announced its line-up for the first half of 2015, including a stage adaptation of Irvine Welsh’s Trainspotting and the stage premier of Richard O’Brien’s Shock Treatment, the sequel to his 1981 hit The Rocky Horror Picture Show.

The remake of Trainspotting will come to the theatre after a successful stint at the Edinburgh Fringe Festival in the summer, having even impressed the author.

“I’m not big on reading or watching my old stuff,” said Welsh, who wrote the novel in 1993, “but I was blown away by this new production of Trainspotting at the [Fringe] Festival”.

The play sees Scot Gavin Ross as drug addict Mark Renton, famously depicted by Ewan McGregor in Danny Boyle’s 1996 film adaptation, and will run at the theatre over Easter.

The long awaited second helping of O’Brien’s zany shlock-horror account of when a newly engaged couple stumble across the Annual Transylvanian Convention will run from April 17 to May 9.

O’Brien, who created Shock Treatment nearly 40 years after his first hit, said: “Shock Treatment has been waiting patiently in the wings for a stage premiere since the film was released in 1981.

“Just as Rocky began life upstairs at the Royal Court, it seems a perfect fit for Shock Treatment to start its stage life in the effervescent atmosphere of the astounding King’s Head Theatre.”

Celebrating its 45th birthday next year, the theatre’s first season of 2015 will also host Lucy Skilbeck’s production of Mrs Roosevelt Flies to London and the return of the internationally celebrated Between by South African Oskar Brown.

Adam Spreadbury-Maher, the King’s Head’s artistic director, said: “I can’t think of a better way to say happy 45th birthday than to announce a range of fantastic work which continues to redefine the theatre’s identity.

“The King’s Head is a unique and special place, as our loyal audiences always tell us.

“If you’ve not visited before, this is the year to do it.”
