The second full-length trailer for Pirate Radio.

In the late 1960s, American radio stations blasted rock and roll 24 hours a day. But in the home country of the Beatles and the Rolling Stones, the only way 25 million people could hear their music was to tune in…to a boat.

Inspired by the British pirate radio revolution in the '60s, the majority of the film's shoot will take place in a large rusty metal fishing trawler moored off the coast of England in the very waters that kept the rock of the '60s booming into the U.K.

In 1966 -- arguably British pop music's finest era -- the BBC played only two hours of rock and roll every week. But pirate radio blasted rock and pop from the high seas 24 hours a day. And 25 million people -- more than half the population of Britain -- listened to these pirates every single day.
