This shouldn't come as any great surprise. Smartphones - especially the iPhone - are being widely used as an element of TV/film production, especially for action sequences. They're seen as enhancing the intimacy of such scenes, removing the size challenge of standalone cameras.
'Soderbergh shot his 2019 basketball drama High Flying Bird on an iPhone 8 with a few modifications. He used much of the video footage exactly as he had shot it, whereas in his previous film, Unsane, he had used a special effect plug-in afterwards to recreate the look of old film stock. The American director is reportedly such a fan of the digital camera that when the British director Christopher Nolan challenged him to return to film, Soderbergh said it would be like “writing scripts in pencil”.'
