With those numbers have come some Hollywood-style paychecks — many of them going to actors who are not well known outside China. The Chinese actress Fan Binbing, for example, earned $17 million in 2016, according to a Forbes magazine ranking of the world’s best-paid actresses — more than familiar Hollywood faces like Charlize Theron and Julia Roberts. (She did not appear on the 2017 list.)

Ms. Fan, 36, has had largely superfluous parts in “X-Men: Days of Future Past” and a version of “Iron Man 3” meant for audiences outside the United States, as Hollywood finds supporting roles for Chinese actors in hopes of selling more tickets in a hot new market. She is set to appear in the all-female espionage thriller “355,” which also stars Jessica Chastain and Lupita Nyong’o.

In China, however, Ms. Fan is one of the country’s most familiar faces. She shot to fame after appearing in the popular imperial palace drama “My Fair Princess” in the late 1990s. She has appeared in numerous films, such as “Chongqing Blues,” which competed at the Cannes Film Festival in 2010. One woman has even had plastic surgery to look like Ms. Fan, according to local news outlets.

Ms. Fan drew less welcome headlines in May, when a popular television presenter accused her of trying to dodge taxes. As evidence, the presenter, Cui Yongyuan, posted on social media what he said were two versions of a contract for the same film. According to one, she was paid about $1.6 million for four days’ work; in the other, she was paid an extra $7.8 million.

It is not clear whether the contracts are real, and Ms. Fan accused Mr. Cui of slandering her. But soon after Mr. Cui made his accusations, the Chinese tax authorities began investigating whether the movie industry was giving big-time actors two contracts, a public one to be reported to the tax authorities and a covert one promising a large bonus. In China, the practice has come to be known as “yin and yang contracts.”
