    In documentaries when a director takes on a sensitive subject matter, like upsetting historical events, he or she needs to develop a certain point of view without being biased, or the authenticity of the documentary is jeopardized. Two historical events that are featured in many documentaries are the Holocaust and the terrorist attacks of 9/11. Director, Alain Resnais, captures the horrors that took place in the Jewish concentration camps during World War II in the 1955 short documentary film Night and Fog; whereas director, Michael Moore, focuses on the actions of President George W. Bush following the 9/11 attacks in the 2004 documentary, Fahrenheit 9/11. Though both films expose the truth behind the said historical traumas, the different montage approaches of these directors evoke distinct point of views: one that is omniscient while the other is objective, respectively.…

    Hoosiers, Film Analysis

    • 12 Pages

    Let me first begin by saying I am a huge sports fan. I played almost every sport growing up and have always loved watching sports, in particular college basketball and any type of football. I saw Hoosiers a few times growing up and enjoyed it every time. In my opinion it is one of the greatest sports movies of all time. The acting of Gene Hackman is definitely an Oscar winning performance. Even though this is not based on a true story it is very believable to me that this event could have occurred, and for that reason it enhances the emotion I feel when they fight through diversity and win the state championship. All of the above are the reasons I chose this film, I knew I would enjoy it and enjoy writing about it.…
