Harrison Ford nearly turned down the role of Henry because the character was a trial lawyer. He had just played one in Presumed Innocent (1990) and was afraid of being typecast. He took the role when he realized that Henry would only be functioning as a lawyer for the first 10 minutes.
In his episode of "Inside the Actor's Studio," Harrison Ford stated that while doing research for his role as Henry, he met a real life lawyer who had a similar experience to the character after a car crash. The man told him that, like Henry, his job had made him a very bitter person, estranged from his family, and had suffered severe brain damage from his accident. He told him that the experience had changed him and helped him to become, according to Ford, "a different person".
A scenario when numerous Japanese clients are seated at a table, turning around and looking at Henry occurs toward the end of the story when Harrison Ford enters the conference room to declare his resignation from the law practice. Real Japanese businessmen who worked at the Yasuda Life Insurance Company's New York headquarters played the role of the Japanese clients in this scene (now Meiji Yasuda Life Insurance Company). They possessed zero film expertise.
The role of Linda was a last minute addition, added two days before wrapping.
