From the Hollywood Reporter:
The live-action project, "Grumpy Cat's Worst Christmas Ever," will bring "fun and irreverence" to the network, says Lifetime exec Arturo Interian.
...
Lifetime is casting the voice of Grumpy for the live-action project, which will shoot this summer. The cable network said the movie, which Interian describes as "a little Home Alone and a little Die Hard," would also feature cameos from other famous Internet memes.
Does anything else need to be said about this? I didn't think so.
