There have been many wise women in the history of cinema.

Two good candidates to highlight during your sermon would be Emily Blunt’s portrayal of the titular character in Mary Poppins Returns (directed by Rob Marshall, Walt Disney Pictures, 2018) and Galadriel from The Lord of the Rings: The Fellowship of the Ring (directed by Peter Jackson, New Line Cinema, 2001). Both actresses play characters in their respective films who possess the same kinds of qualities and attributes that are mentioned in the closing passage of Proverbs.
