In the mid-1960s, he enjoyed a late-career surge in the United States when he narrated the made-for-television animated film of Dr. Seuss' "How the Grinch Stole Christmas," and also provided the voice of the Grinch, although the song "You're a Mean One, Mr. Grinch" was sung by the American voice actor Thurl Ravenscroft. The film was first broadcast on CBS-TV in 1966. Karloff later received a Grammy Award for "Best Recording For Children" after the recording was commercially released. Because Ravenscroft (who never met Karloff in the course of their work on the show) was uncredited for his contribution to "How the Grinch Stole Christmas!", his performance of the song was often mistakenly attributed to Karloff.
