New Harry Potter movie stars seek to charm China

"One of the most amazing things for me to work in a J.K. Rowling film is no scene is ever the same. Every day you will face a new challenge."

Jude Law, Katherine Waterston and Ezra Miller joined Redmayne at the China promotional event.

The Harry Potter series is one of the world's highest-grossing cinematic sagas. The eight films released between 2001 and 2011 earned $8.5 billion internationally. China contributed 1.24 billion yuan ($179 million) to that total, according to box-office tracker cbooo.cn.

China's film industry has boomed in recent years and overtook Japan as the world's second-largest market in 2012. So, the tales of these iconic young wizards－Harry, Hermione Granger and Ron Weasley－may have entered Middle Kingdom a bit too early for maximum market impact.

But the Fantastic Beasts series, for which five features set over two decades are planned, seems to be a hit in the country.
