Post-Covid, blockbuster films will be made about who cornered and tamed the Covid-19 critter and saved us all from wrangling for eternity over whether a Scotch egg counts as a meal. Harbour no hopeful illusions, the virus will never be beaten, only cornered. On a surviving IMAX screen, probably now somewhere distant from you, the post-WWII The Dam Busters equivalent will be COG (Covid-19 Genomics UK Consortium). Go for it, Sam Mendes. After 1917 you’re my favourite to come up with a snappy title, and nail-biting presentation. Masked cinema goers will queue around the block. Instead of lantern-jawed Guy Gibson silhouetted in searchlights, hauling back on the yoke of a thrumming Lancaster over the Möhne Dam, we shall be gobsmacked by the formidable, surgical-blues-clad Professor Sharon Peacock in her lab at Cambridge, wrestling with pipettes.
