They report:

“Webb is taking the films back to the beginning, withGarfielddonning the Spidey suit once worn by Tobey Maguire, and Stone playing Gwen Stacy this time around, rather than Kirsten Dunst’s Mary Jane Watson. From what we’ve seen so far, the film looks to be a darker take on the superhero than the original three films, and I can’t wait to see what Webb’s done with it.
Along with Garfield and Stone, both of whom are very much deservedly rising young stars, the cast also includes Rhys Ifans as The Lizard, Martin Sheen and Sally Field as Ben and May Parker, Denis Leary as Captain Stacy, Chris Zylka as Flash Thompson, and Irrfan Khan as Dr. Ratha, with a script from Steve Kloves (the Harry Potter films), James Vanderbilt (Zodiac), and Alvin Sargent (Spider-Man 2 and 3).”
