What's a good topic for doing English PPT?

For example, introduce European and American pop music, introduce foreign restaurants in this city, introduce classic movies worth watching, introduce jokes of different cultures at home and abroad, and introduce BBC documentaries. Cut in from a smaller angle, create topics of interest to everyone, and be fascinating. You can introduce some movies you like, or introduce some celebrities and so on. You can also talk about a theme, such as friends, such as celebrity friends, such as movies with friends as the theme. You can keep asking questions. Thank you.
