As for Battle of Memories, the film avoids dwelling too much on scientific accuracy - a matter Chinese filmmakers do not handle too well - and instead focuses on suspense and plot twists.

Star power is also working for the film with a celebrity cast comprising Huang, Xu, Duan Yihong and Yang Zishan.

The movie overtook Andy Lau's action thriller Shock Wave to top the domestic titles' box-office charts on Tuesday.

Since the film opened across the Chinese mainland, it has grossed around 200 million yuan ($29 million), according to live tracker Cbooo.cn.

The movie got 7.3 out of 10 on the country's most popular reviewing site Douban.

But for Chen, figures are not the most significant thing.

"My expectation from the box office is just about meeting ends. If the movie can earn a little more than the budget, I will be very happy. This will encourage more filmmakers to work on this genre (soft sci-fi)," he says.

Chen, who was born in a middle-class family in Taiwan in 1982, took up direction at the age of 23.

But despite some of his early movies gaining recognition at international film festivals such as Venice and Busan, he did not make an impression in the mainland market until 2011, when Love on Credit scored big.

Chen then decided to press on and his psychological thriller, The Great Hypnotist, earned nearly 300 million yuan in 2014.

Chen says he adds indie elements to his movies to pay homage to the classics or masters he adores.

Chen, who watches more than 100 movies every year, calls Taiwan master Hou Hsiao-hsien and Spanish filmmaker Pedro Almodovar his heroes.

"The movie that influenced me the most is Almodovar's All about My Mother (a 1999 winner in the Oscar's best foreign language category)."

Looking to the future, Chen says he will split his time between directing movies for the big screen and the internet, as he believes that web productions will change the way movies are watched in the future.
