'Breaking Dawn - Part 1'
The fourth installment of "The Twilight” saga hit theaters on Nov. 18. Summit Entertainment

The Twilight Saga series of films may be reaching its climax but there seems to be no slowdown at the box office, as fans greeted Breaking Dawn - Part 1, the first part of the series finale, in record numbers.

The film, starring Robert Pattinson and Kristen Stewart, enjoyed the third-highest opening day ever and earned an estimated $72 million on its first day in U.S. and Canadian theaters.

Although the film couldn't outperform Harry Potter and the Deathly Hallows - Part 2 (2011; $91.1 million) or The Twilight Saga - New Moon (2009; $72.7 million), midnight screenings of the movie did help it beat The Dark Knight (2008), Transformers (2007) and most of the films in the Harry Potter series; it took in $30.25 million in midnight shows.

A statement by Hollywood.com Box Office suggested the film may make as much $140 million in three days. If the figure does prove to be accurate, the film would then enjoy the fifth-highest opening weekend ever, behind Deathly Hallows - Part 2, The Dark Knight, Spider-Man 3 (2007) and New Moon.

If the predictions prove true, Breaking Dawn is set to enjoy the fifth-highest opening weekend ever behind Deathly Hallows, Part 2, The Dark Knight, Spider-Man 3 and New Moon. While Eclipse opened with $68.5 million, the first Twilight opened with $36 million.

Breaking Dawn - Part 1 is being shown on an estimated 4,000 screens and is based on the final novel by Stephenie Meyer.

Summit Plans to Make $1.2 billion off Breaking Dawn - Part 1

The multi-million dollar opening of Breaking Dawn - Part 1 has already broken box office records. However, according to confidential documents obtained by TheWrap, the final two films in the franchise could generate more than $1.2 billion in revenues and $447 million in profits for the studio and its investors.

According to the report, the number isn't impossible. The previous two films in the series grossed around $700 million each, worldwide. The latest in the installment is expected to make up to $140 million, domestically, this weekend alone.

The three stars, Pattinson, Stewart and Taylor Lautner, will also be raking in the cash. The trio reportedly gets $25 million each for performing in the last two Twilight films. However, Summit declined to confirm or deny this information.
