In recent years it’s become fashionable for sport documentaries to include a self-referential element in which the protagonist reviews footage of their own triumphs and disasters. The facial reactions in these segments often say more than hours of talking head analysis ever could: the vision of Michael Jordan, tablet in lap, choking up with laughter as Gary Payton’s account of the 1996 NBA finals series is played back to him remains the defining image of 2020’s The Last Dance. For Shark, premiering in the US on Tuesday night, directors Jason Hehir (who also directed The Last Dance) and Thomas Odelfelt replace the tablet with a laptop kept open on a small side table next to the seated Greg Norman.
