The film’s preparation and shooting took quite a lot of setbacks. In two or three years, investors and actors changed frequently. Among the many obstacles, the biggest concern of investors is Mike Cassirer, who is the first director. London said: "I think it is too simple with Alexander the Great . We like this script and we know Mike. We don’t think there is any problem with him directing. He and Alexander the Great are film school classmates and have directed a very good one. The short film "Broken Horse" was only later changed into a writer."
Although there are several producers who have never met Cassirer, they have confidence in him when they meet for the first time. Because Cassirer is completely different from a rookie who has just entered the film industry, he is already a successful Hollywood writer. Randall Emmett said: "The most fascinating thing in the story is how to take care of her father. This is not the same as the father-daughter relationship in the past. The young girl is responsible for supporting the family and supporting herself and her father. I haven't seen this kind of plot dynamics for a long time."
