2/2. Jeremy Vine marks the 60th anniversary of the start of the Cold War - underscored by Winston Churchill 's Iron Curtain speech in March 1946 - with a look at its impact on popular culture, particularly film, music, television and literature (and vice versa). This concluding part examines the escalation of the Cold War during the Thatcher/Reagan era, with a look at the phenomenal success of the Rambo films and how film-makers once again responded to the threat of a nuclear apocalypse. David Hasselhoff recalls his Berlin Wall performance, and Paul McCartney reflects on the Beatles' impact on the Soviet Union.
