Producer Raymond Wong said that Sammo Hung is very, very professional in his work:
During the filming of one of the episodes, he took a blow to the head and immediately lost consciousness, which really worried us. When he was given medical attention and brought to his senses, his lips were bleeding. We wanted to send him to the hospital immediately, but he flatly refused, insisting on completing his daily work schedule before taking him to the hospital. This is the typical attitude towards their work among filmmakers of the previous generation.
Raymond Wong added that for now, work on Ip Man will stop after the second film:
When we made the first film, it was based on a true story, we were more careful in our approach because it had important implications for both its descendants and the audience. After the success of the first film, in the second we used more imagination and were more creative. But now the market is oversaturated with other Ip Man films, so we have no intention of making a sequel.
As a result, Raymond Wong began preparing another project with Donnie Yen, a modern action film in which, if we're lucky, we'll see him working together with Tony Jaa and battles from the Great Wall of China to South Africa, including Hong Kong.

I haven't seen Donnie Yen in a modern setting since Flash Point. I am waiting...
