"I play a detective, very close to myself actually"

Jon Voight's quote suggests that he has the ability to make use of his own individual experiences to represent an investigator in his acting functions. This indicates that he is able to use his own knowledge and understanding of the world to bring a sense of realism to his character. He is able to draw on his own life experiences to create a believable and relatable character. This could be since he has a natural understanding of the world and individuals in it, or because he has had experiences in his life that have actually provided him insight into the life of a detective. In either case, it is clear that Jon Voight is able to use his own life experiences to develop a credible and sensible character.
