Brian and Charles is a sweetly funny mockumentary about a lonely Welsh inventor who is not that good at inventing. That said, I reckon his ‘pine cone bag’ would sell pretty well if Vivienne Westwood got behind it. (His ‘trawler fishing net shoes’ would, admittedly, be a tougher proposition.) Then, more by accident than design, he manages to invent a robot, and a friendship develops between the two.
