In Back To Stockport there will be live footage of the band, interviews with each band member and “extensive and candid” behind-the-scenes access.
Watts said: “This is a project that has been very close to my heart for the last 18 months. Given my personal relationship with the band and the town itself, it was hugely important to me that the film delivered.
“I’ve been filming the lads since they started out, so it has been surreal to see their rise to such success – but not surprising. To be able to make a film about them playing to a sold-out show in our home town of Stockport was something I’ll never forget.
“I think the film gives an intimate insight into the amazing bond and togetherness this band has. They grew up as best friends and it really does show on the screen.”
The Blossoms added: “We’ve worked with Charlie on and off since the band started really, so when the opportunity to make something together surrounding the homecoming show in Stockport came about, we jumped at the chance.
“We think he’s really captured the spirit of the band, and being a friend, he was able to get the natural moments you don’t normally see in a band documentary. We love the film and hope you do too.”
