"Michael Grandage Company presents Marcelo Dos Santos' new comedy Backstairs Billy which looks at a pivotal moment in the 50 year relationship between the Queen Mother and her loyal servant William "Billy" Tallon.

Michael Grandage directs Penelope Wilton as the Queen Mother and Luke Evans as Billy.

Set in 1979, when strikes are bringing the country to its knees and Britain is about to seismically change under Margaret Thatcher, it is business as usual for the Queen Mother and Billy inside Clarence House. Receptions are in full swing and the champagne is flowing as the two worlds start to collide with dizzying consequences."
