Due to the length of Breaking Dawn, the movie had to be made into 2 parts.
Renesmee Carlie Cullen is named after her grandparents - Renesmee (Renee & Esme) Carlie (Charlie & Carlisle)
Bill Condon chose not to show Edward ripping Bella's body open with his teeth during the childbirth because he felt having the audience experience it via sound effects and having Robert Pattinson slightly out of frame made it more potent. He also felt it made the scene more special for viewers who have read the book.
The sex scene between Edward and Bella during the honeymoon is only 40 seconds long.
Takes place in a period of one full month. The Twilight character guide points out that Renesmee's birthday is 11 September, thus at the film's cliffhanger scene, it takes place the next morning (12 September).
The visual effects team used a Lola projection rig to age Mackenzie Foy during the imprinting scene. They used footage of an 18-year old model running and digitally aged a CyberScan of Foy, then 10-years old, to match the model's mannerisms. The team used similar software that companies use to age and locate missing children.
To achieve the effect of a newborn Renesmee, the visual effects team used the motions of over 30 real babies using the Lola projection rig. Small bits and pieces were taken to create the final look. Images of Kristen Stewart were also used so the baby would most resemble her like in the book.
Director Bill Condon specifies that Bella's walk down the aisle during the wedding scene was shot through her point of view thus giving it the longer time frame. He thought the walk would feel long to Bella so he incorporated that into the film so the audience could feel what she would be feeling.
Robert Pattinson and Taylor Lautner had difficulty not laughing while filming the birthing scenes, specifically when they had to try and bring Bella (Kristen Stewart) back to life.
Bella's body was prosthetic from the shoulders down in the birthing scene. There was an opening in the table so Kristen Stewart could comfortably lay down underneath the table top while still allowing her head and shoulders to be visible. To achieve movement of the prosthetic limbs a puppeteer was also under the table controlling the limbs.
At Esme Island, Bella's chess pieces while she's playing are white in color, foreshadowing her character's transition towards the start of The Twilight Saga: Breaking Dawn - Part 2. The transition was also related by Stephenie Meyer in regards to the theme of the book's cover (red pawn, white queen).
Stephenie Meyer: She can be seen as one of the wedding guests as Bella walks down the aisle. Producers Wyck Godfrey and Bill Bannerman and screenwriter Melissa Rosenberg are also featured alongside Meyer as wedding guests.
One of the key elements in both the book and the movie was is how Edward tries to distract Bella with activities in order to keep her from thinking about having sex again. In the movie, one of the activities is a game of chess, with both red and white pieces, just like the pieces on the cover of the book. Share this
In 2012, author Stephenie Meyer told Entertainment Weekly magazine that while she was filming her cameo in the wedding scene, she sat next to producer Wyck Godfrey, who was also appearing in the scene as a wedding guest extra. Meyer said that she and Godfrey spent their time creating a backstory for their "characters": that Godfrey "was a deputy policeman, and our marriage was on the rocks because he was in love with (Bella's father) Charlie."
Is the first Twilight film in which Stephenie Meyer served as a producer and is credited as one. Although Meyer was present on set during the previous three films she never officially held the title of producer.
