Dear Barrett,
 
Apologies for contacting you out of the blue - my name is Theo Hessing. I work for an independent film production company called Native Voice Films (www.nativevoicefilms.com) in East London.
 
The reason I'm writing is because we recently came across some of your articles about Anonymous - in the Guardian and Daily Kos - with great interest. We're in the process of developing an idea for a BBC Storyville documentary that looks at those involved in internet security and hacking - the exact outline of which is still being explored, as we work out what sort of access is possible to relevant and interesting contributors. As such, we were wondering whether you might have time to chat briefly with us to discuss some of your ideas further?
 
We're particularly interested to hear more about the community of hackers beyond the usual stereotype expounded by 'expert' talking heads, and thought you might well be able to provide some valuable insights to help direct our research. The intention with all our films is to let people tell their stories for themselves, not for any kind of expose or investigative critique - for some examples please have a look at our website.
 
Thanks for your time, and I look forward to hearing from you.
 
Best wishes,
 
Theo.
