From this study it is clear that directing covers the methods, technologies, thought processes, and judgments that a director must use throughout the fascinating process of making a film. Directing also should help you master technical and conceptual skills in the filmmaking process. “The first time we watch a film; we usually don’t know or think about the artistic decisions that were made during its production.”
According to the discussion Scriptwriter Stuart Beattie originally set Collateral in New York City. Max was to be portrayed as a loser, hiding from the world in his cab and getting little out of life. Once Mann took charge as a director, he made numerous changes. The setting was changed to Los Angeles. Max became less a loser and more a laid-back, intelligent man content to observe the world from behind a steering wheel and to interact with his passengers, endlessly delaying his plans to start his own limousine service. The story largely consists of this pair interacting, so Mann’s decision to change Max’s traits altered the nature of the conflict between them. Max becomes our point-of-view figure for most of the film. Unusually for a film about a professional killer, we don’t see the first murder but stay with Max in the cab until the shocking moment when the body falls onto his cab roof. The switch to Los Angeles affected many aspects of the film’s style. One of the attractions was that this tale of a random crossing of destinies took place almost entirely at night, from 6:04 p.m. to 4:20 a.m.
