How to shoot a TV series with one person and two roles? How can the same person have two different roles on the screen?

When a person plays two roles in a TV series, the framework of these two roles is as follows:

1. There is no physical interaction between two characters in the same box.

Before shooting, the film special effects artist will put a board between the lens and the photographic film. When shooting, only a part of the film can be exposed to light because of the shielding plate. At this time, the actor will appear on the left side of the picture to play in the air, and the right half will not be sensitive because of the shielding plate. After shooting, the film will be put back in its original position and the shutter will move to the left. The actor will switch to the right to play another role and continue shooting, and the lens and background will remain in place throughout the process.

After the superposition of two shots in different parts and the later images, the picture is complete, and two characters can meet in the same picture.

2. Two characters have physical interaction in the same box.

First of all, through the help of the stuntman in the shooting process, the physical interaction between the characters is improved. The stuntman doesn't show his face, but does the rest of the body movements for the actor who plays the role. But the actors will shoot this scene again After the scenes of the two characters are shot in turn, the two groups of materials will be spliced, cut and synthesized later to replace the body double, so that the two people can be in the same picture.
