All the King's Men: Thinly-veiled story of Huey Long.
V For Vendetta: Though based on an anti-Thatcher graphic novel, the film is seeped in Bush-era paranoia and is an indictment on the jingoistic propaganda, fear mongering, religiosity, pro-wire-tapping, pro-torture, gay discriminating, and Muslim discriminating stances of the Bush Administration and right-wingers of that time.
Primary Colors: Thinly-veiled story of the rise of Bill Clinton.
Serenity: A strangely enticing pro-libertarian story about a group of people who want to live free and are crushed under the good intentions of a too-big-to-manage government who only wants to make everyone's life better...just at the expense of personal freedom and free-thinking.
The Dark Knight: A strangely political film that manages to remain even-handed in examining the process a state/society/community will go to maintain order. If the government loses the exclusivity on violence through either incompetence or discrediting corruption, how far can it go to protect its community and social order while stepping on its ideals and liberties? In this film Batman both can use wiretapping successfully....before destroying the process to do it again and having used torture multiple times earlier in the film to pointless and ineffective results.
Kingdom of Heaven: Though set during the fall of the Christian Kingdom of Jerusalem in the late 12th century, it's just as much, if not more, about relations between Westerners (Christians then, more Christian/secular-backed Jewish people today) and the Muslim east in the Holy Lands.
Nothing But the Truth: A film about the rights of journalists and their ability to seek the truth in the face of an ever-increasingly muscular government. Thinly-veiled warning of current laws and the outreach of the Bush Administration.
I may post more later.
