Emma Stone has been filming 'The Amazing Spider-Man 2' in NYC, and she was actually spotted having lunch with Judd Apatow a couple of days ago. This has sparked rumors of a possible collaboration between the two, who previously worked together on 'Superbad'.
Of course, it was Apatow's decision that changed Emma's life as 'Superbad' was her feature film debut. Sources close to Emma have said that she would love to work Judd Apatow again, especially considering that she's trying to find more comedies to star in and possibly produce.
Right now, her career is on fire and the next few years for her will be very busy. She had to drop out of Guillermo del Toro's 'Crimson Peak' because of scheduling issues, as she already has the Woody Allen film and the Cameron Crowe film set to shoot within the next year.
Emma Stone has gotten to the point in her career where she's able to have general meetings with filmmakers and collaborate on a project together, much as she did with Cameron Crowe. However, we can't guarantee anything as we don't know for certain, but don't be surprised to hear about a project involving Emma Stone and Judd Apatow.
