The Best Song Ever hitmakers were indulging in a spot of angling while being filmed for their new 3D docu-drama This Is Us when Styles caught himself while casting off his fishing rod, and the bizarre accident was captured on camera.
Director Morgan Spurlock revealed, "We were all fishing and Harry somehow managed to get the fishing line caught. First it was in his finger, and then later in his backside. It'll definitely be featured in the film."
This Is Us is set for release later this month (Aug13).
