Let's look at the friendship starring. There is also a guest called friendship. Generally speaking, it is a supporting role, with few scenes, or the director's friendship with some big-name friends pays more. Most of them came to see the performance out of friendship. There is a big difference between the price and the special performance. I really came to see the performance out of friendship. In any case, in the same TV series, if there is a big-name actor who is almost or even higher than the protagonist, the audience will think it is very worth the price.
Finally, let's take a look at the special friendship performance. This refers to stars who have friendship with film companies, or very big-name stars who have few scenes. From the film producer's point of view, some small characters also need big names to add color, which can enhance the importance of a scene in the film. To sum up, special performances and friendly matches are the natural rights of some big-name stars to play less important roles. It can also improve the box office and increase the interest of the audience.
Special starring. In the first case, the big-name star usually plays an important role, but there are not many scenes, and he is not the protagonist. However, his position is definitely not lower than that of the protagonist, and perhaps higher than that of the protagonist. In order to highlight his level, he added a special performance to show his respect. In the second case, in addition to big-name actors, there are also cases of pushing new people, but it is relatively rare.
