Not much is known about the plot of Mad Shelia, though the trailer indicates that it partially apes Fury Road's setup along with its post-apocalyptic vehicle combat aesthetic. The film was reportedly filmed very quickly in Outer Mongolia with a cast of mostly lower tier Chinese actors and TV performers, and features a heroine similar to Charlize Theron's Furiosa from Fury Road.
No plans are in place to release the film outside of China at this time. Rather than appearing in Chinese theaters, Mad Shelia will debut on the state-run Netflix-esque streaming service Tencent. Rapidly-produced B-movies of this nature are increasingly common in China ever since the advent of Tencent, often produced on noticeably-fast schedules with little union or (official) government oversight and referred to as "wang da" - short for "wangluo da dianying" or "big internet films." The producers are confident that they have a hit on their hands, as they've already agreed to produce a pair of sequels titled Mad Shelia: Virgin Road and Mad Shelia: Vengeance Road, already believed to have gone into production.
The film was directed by the prolific Lu Lei, who is also the CEO of production company New Media Films. He has claimed an eight-month shooting schedule was required to create the film, though it's believed that some of that schedule also went into early work on the two sequels. Meanwhile, no official start date or plans are yet in place for a hoped-for official followup to Fury Road, with director George Miller having yet to decide on his next feature film project. It was rumored earlier this year that Miller is now working on a Fury Road prequel movie, but that report has not been confirmed.
