拍這部電影之際，中國(guó)大陸還在積極地實(shí)現(xiàn)社會(huì)主義的建立之中。封建社會(huì)中的思想與結(jié)構(gòu)逐漸消失，資本主義必然滅亡的思慮越來(lái)越普遍。沒(méi)人能說(shuō)毛主席的時(shí)期是完美的，不過(guò)該時(shí)期的建設(shè)共產(chǎn)主義并且鏟除封建制度的努力是萬(wàn)分真誠(chéng)的。不寧唯是，只能看看當(dāng)時(shí)的香港、臺(tái)灣就發(fā)現(xiàn)中華人民共和國(guó)的進(jìn)步才是真正的、為人民采取的。那年頭的香港、臺(tái)灣，盡管是70年代的社會(huì)，可仍然跟現(xiàn)代而善良的社會(huì)各不相同，而是跟封建主義的社會(huì)極其類(lèi)似。

本故事的背景、主題都在為我們警世，人世間雖沒(méi)有完美的地方，但仍然有比較公平的。那時(shí)候的香港、臺(tái)灣那樣地方并不是這種為人民發(fā)展的社會(huì)。這種社會(huì)的發(fā)展就是為了資本、帝國(guó)主義與殖民國(guó)家服務(wù)。很明顯的是電影中的敵人都代表封建主義社會(huì)的結(jié)構(gòu)，帶有一點(diǎn)現(xiàn)代資本主義的元素。工人存在的意向只是為上層社會(huì)而效力。上司們固有的權(quán)利本來(lái)就是剝削勞動(dòng)者，若勞動(dòng)者無(wú)用了，就冷酷無(wú)情地扔到街上。

從主題上的角度來(lái)講，要害為無(wú)產(chǎn)階級(jí)人必須聯(lián)合起來(lái)才能獲勝。而且，如果在過(guò)去做過(guò)壞事，可以為人民犧牲自己以便贖回自己。影片之中，工人，包括女人，都聯(lián)合起來(lái)對(duì)封建主義的上司斗爭(zhēng)。這是共產(chǎn)主義的理念與價(jià)值觀，只要你是無(wú)產(chǎn)階級(jí)人，都應(yīng)該參與革命、奮斗?！洞a頭大決斗》講得非常清楚，僅僅是這樣的戰(zhàn)斗能實(shí)現(xiàn)一種公平而無(wú)剝削的社會(huì)。這種努力的替代方案非常嚴(yán)峻。

At the time of filming this movie, Mainland China was still actively undergoing the construction of a socialist society. Feudalist thought and structures were slowly wearing away, and the genuine belief that capitalism would be destroyed was nearly universal. No one would say that the era of Chairman Mao was perfect, but said era's building of communism and eradication of feudal ideas was completely genuine (something nearly anyone you ask in China today would wholeheartedly agree with, by the way). Moreover, one need only look to Hong Kong and Taiwan to see that The People's Republic of China's progress was both genuine in its execution, and in its efforts being for the people. In those days, Hong Kong and Taiwan, despite being in the then-modern 1970s, bore no similarities to any good or "modern" country, but rather shared many features with feudalist societies we think of as only existing in the past.

This story's setting and themes act as warnings to us all: even though there are no perfect places in this world, there are still those that are at least relatively fair. The development of places like Hong Kong and Taiwan in these times was not for the benefit of the people, but for that of capital, and for imperialist and colonialist countries. The film makes it almost too obvious for us: all of the enemies in this film are stand-ins for the cruel and exploitative relations throughout feudal China, with some modern capitalist elements thrown in for good measure. The workers only exist serve the upper class, and it is the intrinsic right of said upper class to exploit the laborers under them. As the film shows, when the workers are of no use to the feudal-capitalist class, they get thrown out on the street coldly.

Thematically, we're repeatedly drawn to the importance of workers uniting together, and for the importance of those with strength to protect the workers who are weaker than they are. If one has committed misdeeds in the past, serving and sacrificing oneself for one's fellow workers can be a road to redemption. In the film, workers, including women, unite to unite against their modern-day feudal lords. These are the principles and ideas of communism in action, and the movie tells us in no uncertain terms that this is the only way to build a fair society free of exploitation. The alternative to such efforts is grim.
