Here's an example of how you can describe your favorite movie in English:

"My favorite movie is 'The Devil Wears Prada,' a comedy-drama film starring Anne Hathaway and Meryl Streep. The movie is about a young woman who takes a job as an assistant to a powerful fashion magazine editor, and has to navigate the challenging world of high fashion and cutthroat competition.

What I love most about this movie is the relatable and hilarious story, as well as the brilliant performances from Anne Hathaway and Meryl Streep. The Devil Wears Prada is a movie that always makes me laugh and feel inspired, and it's one of those films that I can watch over and over again."

Remember, this is just an example and you can customize your description based on your own preferences and thoughts about the movie.
