Facebook: Tom Felton interviewed Daniel for his BBC Three documentary Tom Felton Meets the Superfans. I did share the preview on Facebook (also below). The documentary aired yesterday and is available in BBC iPlayer for 30 days after the broadcast. If another video becomes avaliable I'll update.
Update: 30th December 2016. A clip via ABC iview. Rupert Grint can't say 'no'
This video is also shared by danieljradcliffe.tk on Facebook.
