When you're invited to direct a movie adaptation involving one of the most-loved literary creations the world has ever known, you can be pretty certain you won't get a second chance if you mess it up.

Thankfully, that's not a fate that befell David Yates. Not only did David take charge of the last four Harry Potter films, he was also asked to make JK Rowling's official spin-off Fantastic Beasts And Where To Find Them, which has been greeted with hugely positive reviews.

With the budgets attached to the Potter franchise, it is of course possible to secure the services of the best composers in the world. David has taken full advantage of this privilege, variously employing Nicholas Hooper, Alexandre Desplat and James Newton Howard. He also collaborated with Rupert Gregson-WIlliams on The Legend Of Tarzan.

You'll hear plenty of their work throughout the conversation, as well as that of John Williams - who provided scores for the first three Potters. We also find out a little bit about his earlier work, and get a blast of Mongolian throat music, which he used to great effect in his BAFTA nominated short film, Rank.
