Jingle All the Way is a 2011 American stop motion animated children's television special produced for Hallmark Channel, directed by Chel White and produced at Bent Image Lab.
 In reviewing the 2011 television holiday special programs, Mike Hale of "The New York Times" called "Jingle All the Way" "...by far the best of the bunch.
 In addition to its charming art and pleasantly low-key storytelling, “Jingle” stands apart from the other holiday programs by not focusing on the manufacturing or delivery of toys."
 Hale also mentions, "For some honest emotion, and a combination of retro holiday spirit with adventurous animation, tune in for "Jingle All the Way"...(it) looks like something you’d see at a European animation festival or late at night on Adult Swim, but it is also gentle and completely Hallmark-appropriate."
