Cesar Romero as the Joker gets perhaps the least to do, though he certainly seems to be having the time of his life responding to the Penguin’s nautical submarine commands with an unhinged “Yo-ho!” or fluttering in terror while being stared down by Catwoman’s thoroughly inoffensive-looking house-cat. Frank Gorshin as the Riddler is, as always, incandescently insane – after he accidentally hits the Batcopter with one of his skyrwriting riddle missiles, his wonderment is so intense that it blurs the line between ecstasy and disappointment. Burgess Meredith as the waddling Penguin delivers some of the film’s best lines, declaiming with squawking relish as he contemplates the possible death of his henchmen, “Every one of them has a mother!” or urging his submarine crew to dive with the immortal exhortation, “Run silent, run deep!”

Posy – initially Rosemary – Simmonds was born in Cookham, Berkshire in August 1945, the middle of five children brought up on a prosperous dairy farm. She was precociously good at drawing and at an early age learned “that if I drew a fairy very well people would say it was good. But if I then made her smoke a cigarette people would laugh”. Early inspiration came from bound editions of Punch, running back to the late 19th-century, that she could reach off the lower shelves of a bookcase. “The smell of those old magazines which had drawings of Hitler is still for me the smell of war. And it was always completely normal that drawings could have words attached.”

In the past I’ve tried to say, ‘Look, we are all crappy superheroes,’ because personal computers and mobile phone devices are things that only Bat Man and Mr Fantastic would have owned back in the sixties. We’ve all got this immense power and we’re still sat at home watching pornography and buying scratch cards. We’re rubbish, even though we are as gods.
