Doppelganger (2003): Cast & Plot

At a medical instrument manufacturing company, the timid engineer Michio Hayasaki, Koji Yakusho, labors to develop a robotic chair capable of mobilising a clinically paralysed person. He realises he’s not making progress under the constant strain of demanding deadlines and managerial pressure, and the stress begins to erode his confidence, leaving him unsure how to push back.

On a return trip home, a man who bears an eerie, exact resemblance to Michio appears on his doorstep. Convinced he’s slipping into a crisis, Michio wonders if the old legend about meeting your double—and the danger that follows—might be true. The doppelganger, however, simply reassures him that there is nothing to fear, and Michio reluctantly invites him inside.
