The first Detective Dee film, an action-heavy Sherlock Holmes-style mystery set in ancient China, earned $46.9 million in the country – then a towering sum for a non-Hollywood production. It was co-produced by China’s Huayi Brothers and Hong Kong’s Film Workshop. The prequel is produced exclusively by Huayi Brothers, as a full Chinese production.
