Forget about heartwarming stories, because here's cinema's first ever brainwarming story: According to Film.com, the new zombie romcom "Warm Bodies" easily won the box office title this weekend, earning an estimated $20 million in its opening frame.

Meanwhile, "Bullet to the Head" took a bullet to the head, as the Sylvester Stallone vehicle only managed a terrible $4.5 million, putting it at sixth place on the charts behind returning films "Hansel and Gretel: Witch Hunters," "Silver Linings Playbook," "Mama" and "Zero Dark Thirty."
