Gloria Stuart, call your agent! The 97-year-old actress (her career stretches back to 1933’s “The Invisible Man”), who received an Oscar nomination for playing the feisty, 101-year-old Rose Butaker in “Titanic,” would be perfect casting if someone does a movie about another feisty 101-year-old named Rose who is currently in the news. We’re referring to the inimitable Rose Morat of Queens who has become the toast of New York for trying to fight off a heartless mugger with her walker. As this Rose memorably told The Post, “15 years ago, we would have had a tussle.”
