They became megastars thanks to the Twilight Saga franchise, and in their first round of press for the final film, Robert Pattinson, Taylor Lautner and Kristen Stewart reflect on leaving the series that made them famous.

"It's slightly worrying," joked Rob of his uncertain future as a working actor outside of the Twilight Saga. "It's a fragile economy at the moment."

Thinking back to his carefree days before Twilight mania set in, the 26-year-old heartthrob tells ET the franchise has become, in all seriousness, sort of terrifying in its magnitude.

"I felt a lot more free in the first one, it felt quite dangerous," said Rob. "This one, you know your fate is still going to be at the front of it, but you have a lot less control than the beginning so it's kind of scary."

"It's kind of hard not to feel it" said Taylor of the pressure to make each movie better than the last. "I felt a ton [of it]."

Kristen, on the other hand, tells us she felt motivated by the stress.

"It makes it incredibly worth it," she explained. "As soon as you don't have that pressure, what are you doing it for?"
