One way to make money with background acting is to be an extra in a film or TV show. Background actors are paid to fill in the scene and make it look more realistic. To be an extra, you don't need any experience or training, you just need to be able to follow directions.
Background acting can be a great way to make money, but there are some risks to be aware of. You may be required to work long hours with little rest, asked to do physically demanding or dangerous tasks, or be exposed to harmful substances or environments. However, if you are aware of these risks and take precautions, background acting can be a great way to earn money.
