The smash hit sci-fi nostalgia-fest reaches the end game on Boxing Day – so brace yourself for blockbuster whoppers. Plus: Ethan Hawke is a dirt-digging ‘truthstorian’ in a quirky drama full of heart – and more Emily in Paris!

The concluding episodes of the Duffer brothers’ smash-hit coming-of-age, sci-fi nostalgia-fest (maybe the secret of the show’s success is how many genres it manages to incorporate?) will be dropping all over the festive season – and they are blockbuster whoppers. Devotees will be up bright and early on Boxing Day for episodes five to seven (the finale airs on New Year’s Day). Events are dominated by Will’s new powers, which present a massive threat to Vecna. But why is Vecna so wary of the cave in which Max is hiding? As the finale looms, the past and present are set to fall into place – and the now visibly twentysomething cast will be able to move on with their lives.

The big-name US talkshow host goes all Fab Four superfan in this historical take on the lives of John, Paul, George and Ringo. Plus, Naomi Fry delivers a rich deep dive into The Doors’ legacy

The popular show’s two-part special on the Fab Four has, bizarrely, prompted its Beatles sceptic co-host Dominic Sandbrook to refuse to appear. But his mega-starry replacement is Conan O’Brien, in for an engaging chat with Tom Holland through the career of John, Paul, George and Ringo. Their USP? Says Holland: “We’re a history podcast rather than a music podcast so we need to make the case that the Beatles are significant historically.” Alexi Duggins
