Zhao, considered one of the country's most bankable stars, and her husband made the acquisition through holding company Gold Ocean Media Inc in December.
Online commerce company Alibaba bought and renamed the film-making company for more than $800 million last year, as it expands into movies and entertainment content. This month, Alibaba Pictures unveiled its first movie project under its new ownership, a romance to be produced by acclaimed Hong Kong director Wong Kar-wai.
Those moves came as Chinese Internet rivals Tencent Holdings Ltd and Baidu Inc also began to explore forays into movie-making and film content.
But Alibaba Pictures itself continues to struggle. In August, the company disclosed accounting irregularities after an internal review.
Last week, it said it hoped to replace its auditors, Deloitte Touche Tomatsu, with PricewaterhouseCoopers.
And on Monday, it revealed a "significant drop" in 2014 revenue that it blamed on delays in TV-series distribution, the cancellation or delay of slated films, and a drop in magazine advertising revenue.
Alibaba Pictures, whose stock fell 1.26 percent in Hong Kong on Monday, added that it would reveal more when it releases annual results.
