Spider-man casting rumors

So have u heard, Sally Fields (the "Flying Nun", for those of us old enough to remember), is to play Aunt May.  I knew there had to be some genetic pre-disposition to super powers in the Parker Family. Martin Sheen is also rumored to be Uncle Ben.

Rhys Ifans is going to play Dr. Curt Conners/The Lizard, I think with his lanky frame he'd make a good Lizard.
So far, not a lot of info on the plot. And, a side note, Disney will be responsible for the promotion and distribution of this movie.
