He actually turned up with Dave Prowse (unfortunately neither in 'proper' character) to do a Green Cross Code thing at my primary school (Summerswood) just before 'That Film' was released. Sadly, no-one knew who he was. He has the coolest film credit ever: "Chewbacca Consultant".
Love the way everyone talks about him so passionately and positively. Sounds like he was such a lovely and likeable guy. And his Reddit account was the stuff of legend. RIP
