And so we come to Doctor Who's second first night. But as we will soon discover, there's no guarantee that what gets written or planned for ends up being seen bu the public, as shirts change, scripts are juggled and a writer who doesn't really want to spend too much time ends up producing what the team need - and at a speed they appreciate. Join host Toby Hadoke as he presents the What, When and Who of the first episode of the Doctor Who story that changed the face of the series forever.
