When answering this question, you can discuss both sides. On one hand, having famous actors or actresses can attract more viewers because of their popularity and acting skills, which can help a movie become more successful at the box office. On the other hand, a successful movie also depends on a good story, strong direction, and overall production quality. Sometimes, lesser-known actors can deliver outstanding performances and make a film memorable. So, while well-known actors can be helpful, they are not the only factor that determines a movie’s success.

回答这个问题时，你可以讨论双方观点。一方面，拥有著名的演员或女演员可以因为他们的知名度和演技吸引更多观众，这有助于电影在票房上取得更大成功。另一方面，一部成功的电影还依赖于好的故事、强有力的导演以及整体制作质量。有时，较不知名的演员也能带来出色的表演，使电影令人难忘。因此，虽然知名演员确实有帮助，但他们并不是决定电影成功的唯一因素。
