Человек, который смеётся()

Dmitriy is a popular actor, a star of action films. The public loves him for his image of a macho with an impenetrable face. One day, Dmitriy receives an offer from a stern but very rich businessman from Siberia, Sergey, to star in a crime drama about the 90s in the lead role of a cold-blooded killer. Sergey offers Dmitriy's agent a fee 10 times higher than usual. They agree. During the filming, Dmitriy is accidentally wounded by a shot. After a simple operation, he is ready to return to the frame, but faces an unexpected side effect: now he constantly smiles, and any emotions are expressed with laughter. Dmitriy has no chance to stop filming and "upset" Sergey, who clearly knows firsthand what he is making a movie about.
