'Twilight' Screenwriter Melissa Rosenberg Spills Biggest Script Regret: Edward Cullen's 'Spider Monkey'

“The Twilight Saga” has already ended on the big screen, but there is still something about the first film in the franchise that bothers its screenwriter, Melissa Rosenberg.

Rosenberg told Us Weekly that a line said by Edward (Robert Pattinson) still puzzles her up to now. “In the first movie, there's something about, 'Be my spider monkey,'” Rosenberg said. “I'm like, 'Spider monkey? What the hell is 'spider monkey?'”
