Profile of record producer Sir George Martin. He began with Nellie the Elephant, 633 Squadron and Peter Sellers, then came The Beatles and then the golden age of rock. Martin recorded the soundtrack of the second half of the 20th century.

This rich and intimate portrait follows Sir George at 85 with his wife Judy, son Giles, Sir Paul McCartney, Ringo Starr, Cilla Black, Michael Palin, Rolf Harris and Bernard Cribbins among the many contributors.

A story told in flashbacks, Martin Scorsese's documentary intertwines the immediacy of Bob Dylan's controversial 1966 tour of the British Isles with his remarkable personal and musical journey. Drawing from hundreds of hours of unseen footage and rare recordings, in-depth interviews and revealing photographs, the film strikes a remarkable balance - telling the story of one man's journey and at the same time placing that story within the greater canvas of human events.

This opening part traces his journey from a rock 'n' roll loving kid in the Midwest to his arrival as a major force in the world of folk music. In his own words, Dylan tells viewers how he became smitten with folk music as the story shifts scenes from the iron range in Minnesota to Greenwich Village in New York City.

An amazing cast of characters includes Dave Van Ronk, the king of Greenwich village folk clubs, Joan Baez, queen of the folk music world and Allen Ginsburg, America's beat poet laureate. And, most importantly, the wide range of music that influenced the young Bob Dylan is explored.

As Dylan's fame and notoriety grows, his skill as a performer matures rapidly and the songs begin to pour out - Blowing in the Wind, A Hard Rain's A-Gonna Fall, Masters of War, Don't Think Twice It's Alright and many more.

Part one ends with what seems to be the dawn of a new generation - Dylan, hands intertwined with musician Pete Seeger, the Freedom Singers and Odetta singing Blowin' in the Wind at the closing night of the Newport Folk Festival in 1963.

Martin Scorsese continues to explore the emotional, musicial and intellectual journey of Bob Dylan's early career. The story turns dark. At 23, Dylan is already a newsworthy phenomenon and with that success comes expectations - from the old left to become a politicial activist, and from the media to articulate the concerns of America's youth. It's a role in which Dylan is completely uninterested. He is already on the move, finding a new musical vocabulary to capture the complexity of a seismic cultural shift. He injects a heightened sense of poetry into his writing and adds electricity to his music,

electricity that now seems inevitable but at the time saw him labelled a sell-out and a traitor.

Scorsese delicately balances Dylan's internal world with signpost images from the external world. Dylan's music is the backdrop as the war in Vietnam escalates and the nightly news brings home images people would never have dreamed of seeing on their television sets. Scorsese takes the time to let viewers really see the music unfold in revelatory concert performances.

By 1966 Dylan's personal world has become one of constant touring and press conferences. By the end of the film it is plainly obvious that for Dylan there are some journeys from which there is No Direction Home.
