Back in September, we reported that Emma Stone has been offered a leading role in the upcoming adaptation of 21 Jump Street.  Unfortunately, Stone tells MTV that she has passed on the project:

"I don't think I'm going to be part of that, but Jonah [Hill] is one of my favorite people in the entire world."

Directed by Phil Lord and Chris Miller (Cloudy With a Chance of Meatballs), 21 Jump Street is based off the 1980s TV series and stars Jonah Hill and Channing Tatum.  Hit the jump for what Stone had to say regarding her role as Gwen Stacy in Marc Webb's upcoming Spider-Man reboot.  21 Jump Street is currently set for release on March 16, 2012.

Stone also tells MTV that she expects they'll start shooting on the Spider-Man reboot in two weeks and how it's nice to be back to her natural blonde hair:

Today I went and did hair tests, because I have blonde hair now since Gwen has blonde hair. My natural hair is blonde, so it's kind of nice. I looked in the mirror and said, "Oh my god, it's me again, it's been so long!" We're finalizing the visual stuff. And I think we'll start actually rehearsing, because we start shooting in two weeks. Andrew [Garfield] and I went and learned about science yesterday. Gwen really likes science, so we learned about science. I was home-schooled, so I never went to chemistry class in a traditional setting like Gwen is into. That was really beneficial.

The upcoming Spider-Man reboot will be in 3D and also stars Rhys Ifans, Martin Sheen, and Sally Field.  It's set for release on July 3, 2012.
