A new documentary explores how Astrid Lindgren’s beloved children’s books about the pigtailed free spirit were written in response to the darkest days of the second world war

She’s the mischievous little red-haired Swedish girl with the pigtails. Since 1945, this waif with no mother or father has rarely been out of the bestseller lists and continues to inspire musicals and movies. Heyday Films, the outfit behind Paddington and James Bond, is now developing an English-language adaptation of her stories.

What isn’t generally known outside her native Sweden are the circumstances in which author Astrid Lindgren created Pippi during the darkest period of the second world war, under the shadow of Hitler and Stalin.

Baby Ruth Villarama’s documentary Food Delivery depicts those struggling with the superpower to retain their trade. The director describes capturing their boats getting rammed by the Chinese coast guard

During a televised debate in 2016, populist presidential candidate Rodrigo Duterte made a typically belligerent statement that he himself would jetski to Scarborough Shoal in the South China Sea and plant a Philippine flag there. Duterte claimed that he was ready to die a hero to keep the Chinese out of the bitterly contested maritime territory.

“That made millions of Filipino workers and fishers vote for him because of that one promise,” says film-maker Baby Ruth Villarama. As her new Oscar and Bafta-contending documentary Food Delivery: Fresh from the West Philippine Sea reveals, it wasn’t a promise Duterte kept. “He would make excuses that the jetski has broken down. Eventually there was an official pronouncement that it had just been a campaign joke. From then on, the fisherfolk were really enraged.”
