One of the most significant concepts about the film is that it is meant to portray African-American experiences in a hostile society. Similar to his ancestors, Zinga focused on achieving his dreams regardless of the cost of his endeavor. Also, he manages to go through experiences similar to the ones that other Africans went through as a result of their struggle for recognition.

In spite of the fact that some might consider that the film is too idealistic and that it presents the perfect life of an individual of African ancestry, it is actually meant to trigger deep feelings in audiences that had trouble understanding the negative effects that discrimination had on society as a whole. The director practically wanted viewers to understand the complex feelings experienced by Africans as a result of the fact that they were forcefully taken away...

Moreover, he also wants individuals to comprehend that conditions in Africa were also critical as natives had trouble understanding the importance of progress. In spite of the fact that Zinga initially attempts to demonstrate the powers of technology by providing his people with medicine, the natives are unwilling to abandon their principles and it is only by addressing their core values that he manages to express himself.
Discrimination is one of the principal elements in the film and this is also reflected by the attitudes employed by individuals in England and in Casanga in regard to women. Zinga's wife is harshly discriminate by both cultures and she finds it very difficult to express herself in patriarchal communities.
