THE SUPERCALIFRAGILISTICEXPIALIDOCIOUS CHERRY BLOSSOMS

THE Banks family home — 17 Cherry Tree Lane — is one of the most recognisable addresses in children’s fiction.

To recreate it, the film-makers built a street in Shepperton Studios, lined with cherry trees.

Production designer John Myhre says: ‘The film opens in winter. Then, at the end of all the Mary Poppins magic, spring comes overnight to London. So we needed a street that could magically burst out in cherry blossom. Between 900,000 and one million cherry blossoms had to be put on by hand.’

John took Dick Van Dyke to see it. ‘His face lit up and he said: “This is not our Cherry Tree Lane, but it’s Cherry Tree Lane.” ’
