Stephen King has been known to play cameos in movies based on his books and his brief role in “It: Chapter Two” gave him a chuckle.

King appeared on the Wednesday episode of Global‘s “The Late Show”. The iconic author told host Stephen Colbert about his cameo appearance in the new Pennywise movie.

“I’m playing a crotchety old antiques store dealer who basically screws the main character out of his childhood bike and charges him $300,” King chuckled, “which is a really Yankee thing to do.”

King, 71, also touched on his new book The Institute and how U.S. President Donald Trump has influenced King’s writing over the last three years.

“I try to keep my politics and my stories separate but they bleed over because I also have a life,” King said. “And these have been kind of dark times.”
