FILMS AND THEIR POPULARITY
It goes without saying that cinema plays an important part in our life and society remaining one of the most available and popular forms of art. A great number of people find either going to the cinema or just watching a movie at home an exciting way of spending leisure time. Why?

The first reason is that films provide good relaxation for people of all ages and interests. In actual fact, if something funny, romantic or thrilling is on the screen, we can escape our own lives, forget about our everyday cares and feel the heroes’ distress and happiness, in other words, we share others’ emotions. Thus, in a motion picture we are bound to find something entertaining and exciting.

In the second place, it is a well-known fact that through films we learn a lot of different things, get acquainted with foreign countries’ cultures, increase our knowledge of history, as well as of technology, science and other fields of human activity. Besides, very often films teach us good moral lessons, therefore they prove to be very instructive.

The next point is that on the screen we can see famous people, those who are known all over the world. It is true that the younger generation greatly admires celebrated film stars, and consider them as role models. For instance, seeing Angelina Jolly acting in a film most girls try to imitate her in clothes, speech or bearing.

1. Films help people to feel relaxed.
2. In a motion picture we are bound to increase our knowledge of technology.
3. The older generation admires films about history.
4. Those who act in a film are film stars.
