sucking it all up.

With the release of Breaking Dawn, part four of the Twilight Saga hitting the big-screen today, experts are taking their bets on the much anticipated release.

Edward and Bella unite in 'Breaking Dawn'.

Summit Entertainment, the company behind the production of the films, are expecting a massive $120 million to $125 million gross for the opening weekend. 

If this plays true, Breaking Dawn will make it to the list of Top 10 highest-grossing films of all time. The second part to the saga, New Moon, still takes the lead, with a $142 million in sales for its debut, in 2009. 

Film critics are claiming that the new release will not top the latest and final, Harry Potter, which took out an overwhelming $169 million. 

One thing is for sure, Twi-Hards are ready to sink their fangs into this one.
