How to Be an Extra
Extras, or background actors as they are also called, are a vital part of film and television, despite often being limited to the sidelines of a scene. The truth is, a lack of extras can completely ruin a scene, since they help to give sets a “real world” feeling. Extras are needed to make places feel populated, busy, and generally normal. Most television shows heavily feature public, densely populated areas—hospitals, schools, restaurants, cafes. Not having extras to fill in those spaces would severely alienate the viewer from believing the story and setting.
