Box office watchers predict domestic (U.S. and Canada) sales for the three-day weekend will hit $125 million to $150 million, but with the midnight record that range could be low. Even if the box office total hits that forecast, it would be the highest-grossing Harry Potter debut and put the movie within striking distance of the biggest opening weekend ever.

The record belongs to 2008 Batman movie, The Dark Knight, which collected $158.4 million in its initial three-days.

Deathly Hallows, Part 2 is the eighth and final movie in the Harry Potter franchise and the first in 3D. It also is showing on large format IMAX screens, and sold a record $2 million for a midnight IMAX opening, according to Warner Bros.

The earlier films have generated more than $6.4 billion in ticket sales since the first movie a decade ago, plus billions more from DVDs and merchandise. The movies are based on novels by British author J.K. Rowling.
