Task 2. Read the article again and decide if the statements are true (T) or false (F). An extra in a movie is an actor who doesn't speak. We see these actors in the background of a movie scene. Many movies have hundreds of extras. This is especially true for action movies that have got scenes where many people are running from some dangerous event.
