Directions Unit- Research into similar films (4 minute Film Research)

Recently I have taken it upon myself to check out some films that have a similar plot to the 4 minute film based on a "Journey Through Freedom" that I will be making soon. One film I came across was the 2005 film; "The Island" directed by Michael Bay.
The film itself takes place in a supposedly post-apocalyptic world where the characters believe they have been saved and are being raised in a sterile environment where the governing bodies mission is to keep the human raise alive. Because of this, the characters are never allowed to leave the place they live, otherwise they will learn the truth about their situation, which is that the world hasn't ended at all, and in fact the characters are simply clones of actual human beings and are being kept and harvested for their organs.
Although alot of the plot is irrelevant to the plot I have created for my own 4 minute film, I did learn a lot about the psychology of characters being kept as pseudo-prisoners, under the false pretense that it is for their own good.

I also learnt a great deal about costume. In the film, everybody within the cloning facility dresses the same, in very clean-cut, sterile looking clothing. The fact they all wear the same clothing is similar to that of the prison uniforms some prisons issue to their prisoners. This also highlights the fact that although the conditions the prisoners in "The Island" are in are very nice to say the least, and they are catered for in every way, they are still prisoners non-theless, and have no freedom when it comes to their choice of clothing.

This got me thinking about the possibility of me making the characters in my film wear the same kinds of clothing. That way it would not only make the characters appear as they are (prisoners) but also allow any authority figures or outsiders look different as they are dressed in regular clothes.
