``The Bourne Identity'' A revolution in realistic and stoic spy movies that changed the flow before and after The Bourne.

Doug Liman's father was a prosecutor who investigated famous cases.

So, how did the movie ``The Bourne Identity'', which is so different from the original, cultivate its unique details? This is partly due to the accomplishments of Tony Gilroy, an exceptional screenwriter, but there is also another background that is less well known. It's about Doug Liman's father.

His name is Arthur L. Lehman. He is famous as the special prosecutor who investigated the Iran-Contra affair, which rocked the United States during the Reagan administration in the 1980s, and later wrote a memoir.

To briefly explain this incident, ``The U.S. government secretly sold weapons to Iran, which had cut off diplomatic relations, and provided the proceeds to anti-government guerrillas in South America for the purpose of preventing communism.'' "I was doing it." In other words, it was a major scandal in which an organization-wide act was carried out at the center of the government to deceive the world.

Doug Liman grew up hearing stories about the incident from his father. Then, around 1997, just as Doug was beginning to formulate the idea for ``Bourne,'' his father, Arthur, passed away. Perhaps at this time, he had the opportunity to face deeply once again what his father had left behind.

In this context, he became convinced that the essence left behind by his father could be the key to bringing a certain kind of reality to the movie version of ``The Bourne.'' In this way, the vivid reality of ``Treadstone'', which does not appear at all in the original work, emerges through various inspirations from stories told by his father and his memoirs.

The character played by Chris Cooper is said to be based on Lieutenant Colonel Oliver North, a man whose father Arthur interrogated in court as a key witness in the Iran-Contra scandal. In addition, the details detailed in the memoir are wide-ranging. It seems that every element had an influence on ``Bourne,'' including the bureaucratic structure within the organization, the atmosphere in the operation room, the portrayal of characters, and the chain of command.

After that, Doug Liman often worked on social themes such as `` Fair The Game '' (2010), and in `` American Made with Tom Cruise, - He did a great job of depicting the Contra incident from a different angle. Apparently, this theme of ``cutting into the injustices of power'' is also the battle of his life. He continues to run, inheriting his father's will in a completely different way.
