When the opportunity to interview the Canadian writer, director and animator Dean Deblois presented itself, we just had to say yes, even though our schedule is choc-a-block.

For alongside Chris Sanders, Dean is the man behind the How To Train Your Dragon trilogy - a series of films that have brought Edith and her two boys an immense amount of joy. They're also responsible for Lilo And Stich, another big hit in the Bowman household.

The final installment of the trilogy is called Hidden World. Scored by John Powell (with a little help from Jonsi of Icelandic band Sigur Ros), it brings to a conclusion the story of Hiccup the Viking and his dragon, Toothless. The animation is mind-blowing, and beautifully compliments a narrative that's both wildly thrilling and deeply moving.

As always, we'll be interspersing relevant music with the conversation, including the Jonsi tracks that feature on the end credits of the first two films - Sticks & Stones and Where No One Goes.
