The score was composed by David Newman, and according to Whedon was intended to "deglorify space — to feel the intimacy of being on a ship as opposed to the grandeur". He used two long steadicam shots for several minutes of the film's opening sequence to establish "a sense of safety in space". In 2006, it won a Hugo Award for Best Dramatic Presentation, Long Form. The elements of science fiction that Whedon wanted to convey were essentially different in kind, and held "a sort of grittiness" and "realism", which he said, together, "get the most exciting kind of film-making". Like "Firefly", the film contained a statement on individual liberty. Critic Roger Ebert observed, "Like "Brave New World" and "1984", the movie plays like a critique of contemporary society, with the Alliance as Big Brother, enemy of discontent". The film received the 2005 Nebula Award for Best Script, the 2006 Prometheus Special Award, and was voted the best sci-fi movie of all time in a poll set up by "SFX" magazine. There have since been multiple rumors regarding sequel possibilities.
