Ang Lee’s new movie “Gemini Man” was shot in 120fps/4k/3D format. The High Frame Rate is said to be the “most pristine and immersive format” in movies. It was attempted by Lee (“Billy Lynn’s Long Halftime Walk”) and Peter Jackson (“The Hobbit”) in the past, but the technology has gotten better, to the point where the writer-director is convinced that he’s on to something very special here. At CinemaCon last week, presenting footage from “Gemini Man,” Lee urged other filmmakers to follow in his steps and explore new tech advances with the camera.
