'Twilight: Breaking Dawn' to film this year?

The Twilight Saga: Breaking Dawn could begin filming later this year, according to the movie's producer.

Speaking to the Los Angeles Times, producer Wyck Godfrey revealed that it had still not been decided whether the fourth instalment in the vampire series will be split into two movies but that production will hopefully begin in Vancouver this year.

He added that Robert Pattinson, Kristen Stewart and Taylor Lautner are contracted to return and that screenwriter Melissa Rosenberg is currently working on the script.

"It's a work in process. The issue [of whether there will be one or two movies] is not going to be resolved until we get the full treatment and see whether it's organic," he explained.

"If it's not organic, I don't think it will be done, and if it is, it will be. It really has to do with how much level of detail from the books there is, with all of these new vampires that appear in Breaking Dawn, the whole section about Jacob... It's a very long single movie if it does become a single movie."

Wyck also reportedly said that it had not been decided how to deal with the character of Renesmee, the half-vampire, half-human daughter of Bella (Stewart) and Edward (Pattinson).

He added that no decision had been made on who will direct.

Breaking Dawn is the fourth instalment in Stephenie Meyer's vampire series.
