Details The Twilight Movie Franchise Gets Wrong From The Books

The most (in)famous part about "Breaking Dawn -– Part 2" is Bella and Edward's terrifying CGI baby, Renesme. Instead of using an equally terrifying doll, the producers of the film opted to go with CGI, with decidedly unsuccessful results. It's one of the worst parts of a generally off-the-rails film, even if it does bring us some amusement these days.

Luckily, as Renesme grows up, less and less CGI was necessary to create her character. In fact, one the biggest differences between Renesme in the books and in the films is how quickly she grows. In both versions, Renesme grows very fast due to the fact that she's a vampire/human hybrid. By the end of the final book she looks to be about two years old, despite being only a few months old. In the film, however, the oldest version of Renesme is played by actress Mackenzie Foy, who was 10 years old at the time of filming.

While toddler-aged Renesme was an eerie mash-up of Foy's face with the face of a much younger child, the older version of Renesme is, thankfully, just Foy. It's obviously more dramatic to have Renesme grow at an even more rapid pace than in the books, and it cut down on the amount of CGI they had to use for her character, so we can't fault producers for making this particular change.
