It's the big release we were never quite sure we'd see: Christopher Nolan's "Tenet" has come to European screens, boosting box office figures after a lacklustre summer for cinemas. Our film critic Lisa Nesselson gives us her take on Nolan's cerebral, extravagant offering starring John David Washington, Elisabeth Debicki and Kenneth Branagh. We also take a look at what's coming up on the festival beat as the Lido welcomes a scaled-down selection to this year's Mostra in Venice and Deauville goes ahead with its festival of American film despite the coronavirus pandemic.
