Zombie Movie

I have had this idea for a zombie movie for a while now but I don't think I will ever get around to doing. I want to do a Christmas style zombie movie. A zombie apocalypse during the winter. I just see an empty snowy street with snow falling and Christmas lights hanging from the light poles with Christmas music playing then people running from a zombie hord. Its creepy and disturbing but something about the Christmas music and a zombie eating a person is an awesome combo. I want to do it but it might be a while.
