A boxing movie called Jawbone is doing well in British cinemas, and this week sees the arrival of The Happiest Day in the Life of Olli Maki. It's a quirky, fact-based movie (it won the Un Certain Regard prize at Cannes in 2016) about a boxing also-ran that has some vague similarities to Chuck, but the sunny title tells you that this import from Finland (it's subtitled, in black-and-white for period effect) is not your average fight film.
