"A mash up or bootleg is a song or composition created by blending two or more pre-recorded songs, usually by overlaying the vocal track of one song seamlessly over the instrumental track of another."
There are few good Science Fiction movies lately, that I should be grateful for Oblivion. Stunning visuals, intriguing setting and a steady pace are the main theme of Sci-Fi films coming out this last decade. The most apt description of Oblivion (at least for this film buff) is, a Charlton Heston Sci-fi mash up. Planet of the Apes, Soylent Green and The Omega Man had the same connection: the angry-lone-survivor (portrayed by Heston) fighting his way through a dystopic land. And this is what that movie riffs on. Survival and vengeance. The remnants of New York city monuments (Planet of the Apes), the hero in constant agony (Soylent Green) and the nuclear couple (The Omega Man), are this mash up's vocals.
The supporting cast (Freeman, Coster-Waldau and Bell) is dwarfed by Cruise's macho acting and each actor offers only a snipet of the character that could probably be developed in the original Comic Book,
...which never was:
"Radical Comics allowed me to continue working on the story by developing a series of images and continuing to refine the story more over a period of years. Then I basically used all that development as a pitch kit to the studio. So even though we really never released it as an illustrated novel the story is being told as a film, which was always the intention."
According to Bleeding Cool (who offered an advanced preview of the "comic" a long time ago), due to a screenwriter's strike, the film was suposedly developed as a Graphic Novel, that was then going to be adapted for the screen, just to keep the film's hype alive.
