Before being approached by Benioff and Weiss, Martin had had other meetings with other scriptwriters, most of whom wanted to adapt the series as a feature film. Martin, however, deemed it "unfilmable" and impossible to be done as a feature film, stating that the size of one of his novels is as long as The Lord of the Rings, which had been adapted as three feature films. Similarly, Benioff also said that it would be impossible to turn the novels into a feature film as the scale of the novels is too big for a feature film, and dozens of characters would have to be discarded. Benioff added, "a fantasy movie of this scope, financed by a major studio, would almost certainly need a PG-13 rating. That means no sex, no blood, no profanity. Fuck that. " Martin himself was pleased with the suggestion that they adapt it as an HBO series, saying that he "never imagined it anywhere else". "I knew it couldn't be done as a network television series. It's too adult. The level of sex and violence would never have gone through. "
