Marking the DVD launch of The Story of Film - An Odyssey, Mark Cousins' 15-hour personal history of cinema, the director and film critic joins Sight & Sound editor Nick James to discuss his work.
Cousins maps out the challenges of using hundreds of film clips from a diverse range of rightsholders, and explains why he regards his work as an epic film rather than a TV series, despite its broadcast over 15 weeks on More4.
