He has appeared on Sesame Street in several segments.
In episode 3806, Neeson appears in a segment with the Count. In it, the Count makes a film of Neeson counting to 20, calling it Transylvania 6-5000. Neeson, dressed in clothes similar to the Count complete with monocle, counts so well that it thunders and rains. The Count then decides to make another film of Neeson counting, calling it Countin' in the Rain.
Neeson spoke to Empire magazine about his favorite Muppet: "When I was in theatre in Belfast in the '70s, The Muppet Show was a firm favourite. I liked Kermit and Miss Piggy. Even as ostentatious and egotistical as she was, she loved his green simplicity. She was madly in love with him and that was beautiful."
Voice credits include Aslan in The Chronicles of Narnia: The Lion, the Witch and the Wardrobe and The Simpsons, and Neeson has appeared in Batman Begins, Star Wars: Episode I - The Phantom Menace, Miami Vice, and Woody Allen's Husbands and Wives.
