Macaulay Culkin recently took to Twitter to praise Harry Potter author J.K. Rowling on the casting of Fantastic Beasts: The Crimes of Grindelwald and ask for a role in one of her future projects. Hey @jk_rowling I'm with you! Nagini can be whatever she wants to be! She's a strong woman/snake," he wrote."Also, can you write me into the next movie? I'm Macaulay Culkin (From Home Alone: The Movie) and I was also a Pagemaster (experienced with magic)."
