This new series will certainly appeal to anyone who ever took a trip to London's West End, where showbiz is booming. With millions to be made at the box office, competition is fierce and everyone from producers to performers is searching for a coveted spot on the stage. This documentary goes behind the scenes to follow every aspect of the business of musicals, beginning with a look at Sam Mendes' reimagining of Charlie and the Chocolate Factory.

Strange Days, 9.00pm, BBC Two

In this new series, Dominic Sandbrook charts the effect on the UK of the global superpower stand-off after the end of the Second World War, beginning by considering the impact of a newly divided world on the former British Empire. The historian traces the collapse of the wartime alliance by examining Winston Churchill's "Iron Curtain" speech and the 1945 tour of Britain by Dynamo Moscow, the Soviet Union's leading football team. He also investigates the influence on literature and cinema.
