The scene in 'The Twilight Saga: New Moon' where a near-death Bella is sinking to the bottom of the ocean was to be filmed by putting weights in Kristen Stewart's pockets and letting her sink in a swimming pool. Stewart was apprehensive about this, so director Chris Weitz demonstrated to show there was nothing to be afraid of. As soon as he hit the bottom, he panicked and pulled the weights out of his pockets. He resurfaced, saying "We can't do that to Kristen!" They then filmed her from the side and moved the camera backwards to achieve the effect of sinking.
Kristen Stewart turned eighteen while filming 'Twilight'. According to Oregon law, under-age actors could not work during night hours. On her eighteenth birthday, she was rewarded with a birthday cake decorated with a clock — and a full night of shooting.
Two of Robert Pattinson's songs were included in 'Twilight' — without his knowledge. Nikki Reed was the one who got producers to add Pattinson's songs 'Never Think' and 'Let Me Sign' to the movie. She secretly recorded him playing his guitar and singing, then took it to the film producers. They loved the songs, and the next day asked Pattinson if he would sing a few songs on the soundtrack.
When Robert Pattinson was cast as Edward, he moved to Oregon and began working on his character. He spent five hours a day with a trainer learning to fight, do stunts and play baseball. He also had to learn to drive and got his Oregon driver's license. Before filming began, he tried not to talk to anybody in order to get a sense of how isolated Edward must feel.
The shirt that Bella wore in the famous "first kiss" scene in the first film actually belonged to 'Twilight' director Catherine Hardwicke. Hardwicke has joked that she hasn't washed it and plans to sell it on eBay at some stage.
