Grumpy Cat's Worst Christmas Ever  Grumpy Cat's Worst Christmas Ever (referred to onscreen as Grumpy Cat's Worst Christmas Ever! The Movie) is a 2014 made-for-television Christmas comedy film directed by Tim Hill, who also co-wrote the screenplay with Jeff Morris. The film stars Internet celebrity cat Tardar Sauce, also known as "Grumpy Cat", and Megan Charpentier as a young girl who befriends and later adopts Grumpy Cat, only to discover that the two can communicate with one another. The film premiered on Lifetime on November 29, 2014, to generally negative reviews from critics. Grumpy Cat is a lonely and grumpy cat living in a mall pet shop located that is slated to be closed. She is bitter at being constantly passed over for other animals in the store, but is surprised to find that she can communicate with Chrystal, an equally lonely 12-year-old girl who is shocked that Grumpy Cat can talk. The two are initially at odds, but start to befriend each other, especially after a high-priced Leonberger dog is kidnapped from the pet shop for its value. The film was created to showcase Tardar Sauce, the subject of an Internet meme which first appeared in 2012. By the end of 2013, the company which manages Grumpy Cat's image was valued at around $1 million. The company is managed by Ben Lashes, who is credited as an Executive Producer on "Grumpy Cat's Worst Christmas Ever". Tim Hill, one of the writers, had previously directed "" and "Alvin and the Chipmunks". When Plaza was cast to perform Grumpy Cat's voice, she was initially unfamiliar with it, but learned about the cat before production. The film was shot in its entirety before Plaza recorded her lines. She re-drafted around 90% of her dialogue, explaining, Once I realized that the cat's mouth wasn't going to move, I just kind of went for it, and thought, 'Well, if it's just going to cut to the cat and I can say my line, then I can just comment on other things, too.' The movie kind of has a "Mystery Science Theater 3000" vibe to it, so it's like you're getting Grumpy's commentary throughout the whole thing, but then Grumpy is also starring in the story. The film was first broadcast at 8pm EST on November 29, 2014, on the Lifetime channel in the United States. A hashtag on Twitter representing the film, #WorstChristmasEver, trended during the first half of the movie.
