The fourth installment of the Twilight movies, split into two films, will start production this fall in Vancouver and Baton Rouge, La.

Summit Entertainment has confirmed that cameras will soon be rolling on Stephanie's Meyer's fourth teen vampire novel, The Twilight Saga: Breaking Dawn.

Starring Robert Pattinson, Kristen Stewart and Taylor Lautner, part one of Breaking Dawn will unspool in cinemas in November 2011. No word yet when the second part will be screened.

MTV News reports the production company is considering using the 3-D format, which some cast members, including Stewart, are supporting.

"I think it would be awesome," she told MTV News on Friday. "Nobody knows what it's like to look through the eyes of a vampire. What if [Bella] opens her eyes to this extraordinary world? It could be cool."

Screenwriter Melissa Rosenberg promised steamier scenes in the final two movies.

"It will be sexier," Rosenberg said. "I think it's going to be pretty hot. Way hot."

Bill Condon (Dreamgirls) will take over the reins of Breaking Dawn from the third movie's ( Eclipse) helmer David Slade.
