The songs in Chou's directorial venture－Secret and The Rooftop－were popular online in 2007 and 2013. He says it is easier being a producer rather than director.

Discovered by Taiwan pop-show host and singer Jacky Wu, who financed Chou's maiden album Jay in 2000, Chou also believes in supporting younger talents.

Chou says he was impressed by the visual spectacles featured in Hung's sci-fi thriller Battle for Skyark. So, without hesitation, he invited Hung to direct 10,000 Miles.

A sandstorm and a wolf in search of prey－among the natural barriers in the expedition－are all thanks to special effects.

For the film, actors Sean Huang, Darren Wang and actress Megan Lai were trained by Lin every morning for a couple of months.
