Earlier in the year I linked to a video of Charlie's 72-minute "master class" at the Goteborg International Film Festival. There was also a 30-minute video of the accompanying press conference, and I totally neglected to put that one on here. Maybe I forgot or didn't realise it was there at all, or perhaps I am lazy, or most likely I am just a terrible person.
ALLOW ME TO RECTIFY:
Thanks to Ujwal for giving me the heads up!
