A Chinese film partially bankrolled by Russians in which oppressed people are saved by the power of love. Sorry about the spoiler, but the plot of “Iron Mask” (2020) isn’t very important. Nor is the title (There’s a guy in a mask, but he’s not even the main character. The original title, which has something to do with a dragon, apparently didn’t translate well from Russian to English.). Anyway, this is an Olden Times action/adventure film bursting with choreographed fight scenes worthy of Jackie Chan, who is a producer and co-stars. Arnold Schwarzenegger – bless him – plays an English prison warden.
