The London Film Festival continues to pull in an eclectic selection of films from all over the world. And it’s from the countries not known for their movie industries that some of the most impressive and engaging films have emerged.

When Kristy Matheson won the job of BFI London Film Festival director, she spoke of the chance afforded by festivals for filmmakers, artists and audiences “to commune on a grand scale – to experience ideas, ask big questions and celebrate together.”

Just three days into her first LFF, it’s clear that Matheson and her team are delivering on that vision. There is definitely a sense of provocation, celebration and film-buzzing community in the air. 

Mstyslav Chernov’s 20 Days in Mariupol, which won the World Cinema Documentary Competition at Sundance this year, is an emotionally devastating account of the inhumanity of war.

This wasn’t a film to go and see with my 94-year-old father and hope I’d come out with my critical faculties intact and my handkerchief dry. The Great Escaper is an old fashioned, old school weepie about ageing, guilt and the horrors of war. 

Nothing goes out of date like new technology. Who now remembers how plain old Alan Sugar brought word-processing to the masses with the Amstrad PCW 8256, or how the Psion 5 was for a moment the last word in personal organisers?

It has been seven years since Gareth Edwards directed, for me, the best of the new generation of Star Wars films, Rogue One. Having made Godzilla before that, it’s nice to see him return with a more personal project, a big, bold, beautiful, if flawed sci-fi epic. 

Ken Loach has occasionally invested his realist TV dramas and movies with moments of magical realism – football inspiring them in The Golden Vision (1968) and Looking for Eric (2009) – but magical spaces in them are rare. In The Old Oak, as affecting a movie as any the veteran director has made and his 14th with screenwriter Paul Laverty, three sacred spaces (but a single church) work on the characters in vital ways. 

The misty streets and lofty spires of Oxford star in this adaptation of Carolyn Weber’s 2011 memoir, Surprised by Oxford, in which she finds God while studying for an MPhil in English literature.

Less is more, except when it isn’t. Among the latest batch of overlong Oscar-tipped movies by celebrated auteurs such as Christopher Nolan (Oppenheimer with a running time of 181 minutes) and Martin Scorsese (Killers of the Flower Moon, 207 mins), it’s a relief to find the iconic Spanish filmmaker Pedro Almodóvar bucking the trend with a 31-minute short that doesn’t test the audience’s mental and physical stamina.

Lasting just over an hour, The Nettle Dress is like a fairy story. It builds very slowly, each beautifully framed shot contributing toward a perfect little gem that tells a moral tale.

A man spends seven years coming to terms with the loss of both his father and his wife from cancer by spinning nettle fibres into threads, then weaving them into a length of cloth. He recalls sitting beside a hospital bed, spinning while listening to his father’s breathing dwindle to a last gentle sigh, then during his wife’s final illness, spinning his way through sorrow.
