It depends on the style guide you're following.
* MLA (Modern Language Association): In MLA style, you italicize titles of movies, TV shows, books, albums, and other long works.
* Chicago Manual of Style: Chicago also uses italics for these titles.
* APA (American Psychological Association): APA typically uses italics for titles of movies, TV shows, and books.
* Other Styles: Some other style guides may still prefer underlining, especially in situations where italicizing is difficult.
The important thing is to be consistent! Choose a style guide and stick with it throughout your writing.
Example:
* MLA/Chicago/APA: *The Lord of the Rings*
* Older Styles: The Lord of the Rings
