Taylor Lautner, who plays Jacob in the Twilight movie franchise at first thought he would not appear in the sequel because he wasn’t beefy enough to play a bookworm/werewolf. But the core audience of teen girls basically told everyone on every Twilight discussion board, “If Lautner isn’t in New Moon, we walk.”
The producers acquiesced because at the time, Twilight was raking in nearly $400 million at the box office. So Lautner dutifully packed on 30 lbs. of muscle by eating more and working out with weights. Jacob Black, his character, is the platonic friend of Bella Snow (Kristen Stewart). He transforms in New Moon into a werewolf. The sequel sees Edward (Robert Pattinson) packing up and leaving, Jacob turning into a werewolf, and a love triangle forming among the three.
To prepare for the sequel, Lautner spent two hours a day at the gym and ate every two hours, going to a men’s size small to a men’s large, according to a recent interview Lautner did with Interview magazine.
Lautner then explained that Jacob’s transformation into a werewolf was as much a psychological change as physical. He goes from being a clumsy nerd to being incredibly agile. Alas, he told Interview, during the coolest fight scenes, Jacob the werewolf is played by computer generated imagery.
