Emma Stone is concerned fans won't be satisfied with her performance in The Amazing Spider-Man.

The 23-year-old actress portrays the role of Gwen Stacy in the movie - opposite Andrew Garfield as the titular character - and she admits not everyone is going to be pleased with how she has represented the character.

"This is 50 years worth of comic book material. There are different incarnations of Gwen, and I realized that you can't please everybody. They're hoping that you can bring this character to life, in the best way that you know how. I hope that people are satisfied. I know that not everybody will be, and that's one of those trials of being human, when you learn that not everybody can like you. It is a tough lesson, isn't it?"

Despite her worries, director Marc Webb admits it was an easy decision to cast Emma - who is best known for roles in Easy A and The Help: "When we did a screen test, what was great was that Emma brought a level of humor and levity that Andrew really responded to, and there was this immediate sense of lightness in the interaction."
