Early Friday morning, one of the most anticipated movies of the year, The Dark Knight, debuted at midnight across the country. And it's already making box office history, earning more than $18 million in it's first day. The frenzy continues here in the Hub City, as many of the showings are and will continue to sell out.
'The Dark Knight' is rated PG-13. But many experts warn that parents should think twice about taking small children to see it.
