Joe told Christine Bleakley on ITV’s Lorraine that he loved working with his fiancee again, eight years after their first worked together.

Written by the BAFTA award-winning writers and producers behind The Inbetweeners, Iain Morris and Damon Beesley, The Festival stars Joe as Nick who is dumped by Hannah’s character at his uni graduation and heads to a music festival with his pals in a bid to move on.  

‘He’s kind of going there to get over her, it’s all about letting yourself go and losing yourself at the festival.’

‘Towards the end he kind of lets go, it’s about enjoying yourself and enjoying life,’ Joe explained to Christine.
