During a fire accident in 2019 while the 4K digital restoration was in progress, some of the original 35mm camera negative was lost. In the ensuing months the negative was attempted to be restored as much possible, but a portion of it had been permanently damaged. Lost was not only some of the picture but also the sound in those reels. As a result, Wong had to shorten some of Tony Leung's monologues, but with the work of the restoration crew of L'Immagine Ritrovata, they managed to restore most of the scenes to better quality.
