The casting continues an association between Sony Pictures Entertainment and the actress, who previously starred in Superbad, The House Bunny, and Zombieland, all for Columbia Pictures.

For Superbad, the 21-year-old -- who is known as a redhead -- turned brunette. Her actual hair colour though is blonde!

Stone's recent credits also include Paperman, Ghosts of Girlfriends Past and The Rocker.

Even the director couldn't stop raving about the actress, who is best friends with country singer Taylor Swift.

"The chemistry between Andrew and Emma was stunning and made Emma the clear choice. At the heart of the story of Peter Parker is not only the amazing Spider-Man, but also an ordinary teenager who is wondering what he has to do to get the girl. Andrew and Emma will bring everything audiences expect to these roles, but also make them their own. Much to my surprise, it was fun to find out that our choice for Gwen (Emma) is also a natural blonde," Webb said.

Emma is currently starring in Screen Gems' hit comedy Easy A.

Next year, she will star in Warner Bros' Crazy, Stupid, Love opposite Steve Carell and Ryan Gosling and in The Help, the adaptation of Kathryn Stockett's bestselling novel.

She also has a cameo role in Screen Gems' Friends with Benefits and will voice a role in DreamWorks Animation's comedy The Croods.
