As everyone knows, Lu Ban's actors are all exclusive to his projects and are rarely reused.
Most of the actors in each of his films and short movies are amateurs, and they only take part in one production, with the exception of a few who make repeat appearances; for the rest, it's a once-in-a-lifetime meeting.
This is rather extravagant and also quite regrettable.
Note that in Lu Ban's films, apart from himself, the acting skills of all other actors are rather remarkable; even a background extra seems to possess the acting prowess of a film emperor, making the immersion feel very full.
Such actors, any crew would cherish them as treasures if they came across them.
Yet, after Lu Ban uses them, he discards them, not even allowing them to appear a second time.
Such resources are truly enviable.
