Moviegoers have been turned off thus far by films that weren’t shot and projected at standard frame rates (e.g., 24 FPS), but that isn’t stopping Paramount and critically acclaimed director Ang Lee (“Crouching Tiger, Hidden Dragon,” “Brokeback Mountain”) from pushing high-frame-rate cinema: letters from the studio indicate Lee’s latest, “Gemini Man,” a sci-fi venture starring Will Smith, will be shown in some theaters at 60 FPS (3D) and 120 FPS (2D). Critics of HFR claim it results in “hyper-real and unnatural visuals,” but supporters suggest that’s because audiences have been subjected to 24p film and 30p video for far too long. Paramount's letter includes directions on how to conduct an HFR test and describes the 120 FPS-4K-3D combo as the "most pristine and immersive format" for showing the film. Billy Lynn was the first film to be presented at 120 fps, meaning it had a higher frame rate than the 24 frames per second adopted by most movies. HFR advocates James Cameron (who's shooting the Avatar sequels in the format) and his long-time producer pal Jon Landau have been opining about its benefits since 2011.
