Jo Grant vs the Autons... Again?! | Return of the Autons (webcast)

Return of the Autons was a short created as an extra for the the Blu-ray release of season 8 of Doctor Who. It was originally released over the Internet within a longer webcast titled Jo Grant vs the Autons... Again?!, which also included a trailer for said volume of The Collection, but the minisode (specifically defined as such in the booklet by the story's author Pete McTighe) was included without the commercial material in a definitive form and under its own title in the actual Blu-ray.
