Tony Leung Was Once So Overworked, The Crew Thought He Had Died When He Was Actually Sleeping
The actor apparently was “foaming at the mouth”.

And you thought you were a hard worker.
On a recent episode of the talk show he hosts with Hongkong actor Louis Yuen, Wayne Lai recalled the days he had to straddle a few productions at a time and how he once didn’t sleep for four days in a row. (P/S: That's still one day less than Charmaine Sheh's record of going without sleep for five days when she was a TVB artiste.)
But as shocking as Wayne's story sounds, it was his anecdote about Tony Leung and how overworked the actor was in the early days of his career that stood out.
