But it's a leap from 2016, when only two cinemas-in Beijing and Shanghai, respectively-could show the 120-frame-per-second version of Lee's first high-frame-rate film, Billy Lynn's Long Halftime Walk.

Lee reveals he's considering making a Chinese-language film and that scriptwriting has already started.

"Chinese culture makes me up. I can't hide that, even when shooting Western stories," Li said during the film's Beijing premiere screening on Saturday.

"So, I have a complicated feeling-excited, yet a bit shy-to return to my hometown … I'm expecting Gemini Man will have a good performance in China."
