According to The Insider, the third part of ‘Twilight’, called ‘The Twilight Saga: Eclipse’, will start to be filmed on August 17. This part will be directed by David Slade. In 2007, he also directed another vampire film, '30 Days of Night'.
The third part continues the story exactly where it ends in the second part. So the sequel will be about the love triangle between mortal Bella Swan (played by Kristen Stewart), the werewolf Jacob Black ( played by Taylor Lautner) and her true love Edward Cullen (Robert Pattinson).
