so recently Paul Giamatti is rumored to play the Rhino or the rhino in a sense
and felicity jones is in talks for a role as well, but it is unknown to which role she will take, a young felicia hardy perhaps or an intern at the daily bugle
Dane Dehaan also joined the cast as Harry Osborn
so far for villains we have Electro (Foxx) the Rhino (Giamatti) and the man in the shadows (Massee) which who i believe will be playing Mysterio.
if these villains are concrete i believe this will lead to our friendly neighborhood spiderman taking on the sinister 6 in a future movie. the rhino, electro, mysterio and 3 unknown future villains, but i believe we will have a Dr. Octavius as he always seems to be a part of the different line ups of the sinister 6
note* throughout spiderman history the sinister 6 has had a different roster of villains
