- Cindy Lou Who goes to Who School.
- Executive Meddling: Jeff Schaffer, Alec Berg and David Mandel were brought in to do rewrites with adult humor snuck in. Some of it was cut out due to Howard and Carrey's demands.
- Hey, It's That Guy!: Would you believe that's Taylor Momsen playing Cindy Lou?

- Also, Lou Who is Mr. Noodle. Whobris is Balok. Betty Lou Who is Mary Katherine Gallagher.
- Hey, It's That Voice!: Anthony Hopkins is the narrator.
- Throw It In: Jim Carrey stole Ron Howard's hat and improvised the impersonation. Howard was amused enough to put it in the movie. Carrey also improvised the Grinch's schedule speech.
