Jay Chou (周杰伦) is working on his directing debut with movie “The Secret That Cannot Be Told,” and seems over-exhausted himself.

It’s said that Jay has been working 17 hours a day filming the movie, and has caught the flu and also triggered his old back injury.
Seems like the pop-star is taking the movie seriously… but do take care of himself, the movie cannot be produced if he gets too sick.
Jay will be starring in the movie himself, co-starring Hong Kong veteran actor Anthony Wong (黄秋生) and rising Taiwan actress Guey Lun Mei (桂纶镁).
