Bill Murray
Something about zombie movies just really attracts celebrities to cameos, like Bill Murray to Zombieland. In 2009, Bill suddenly appeared on the screen as a survivor of the apocalypse. Woody Harrelson was able to get the big-name celebrity on the casting list. According to one writer, "Bill Murray said send me the script. He doesn't have an email address interestingly, no agent, no manager, it was Woody Harrelson that called him, his buddy."
