Which new villain will battle Peter Parker in Spider-Man 2?

With Marc Webb signed on to direct The Amazing Spider-Man 2, it's high time we heard some casting rumors! Thankfully, we've got two potential villains — and possible Mary Jane whispers.

According to Variety, Shailene Woodley, who brought the house down in The Descendants, is currently in negotiations to play Mary Jane Watson in the second Spidey movie. Could this mean curtains for Emma Stone's Gwen Stacy?

But that's not all, Variety is also reporting that the name "Electro" is appearing on casting wires — this is an obvious reference to the classic Spider-Man foe Maxwell Dillion, who can control and absorb electricity.

The second name buzzing around the casting wires? Harry Osborn. This makes perfect sense, as OcCorp was already set up in the previous film and the return of the Osborn family to center stage was seriously hinted at in the final scene of The Amazing Spider-Man.

Granted, these are all just rumors, but they're not particularly wild accusations. We still have a long way to go until the film's release in May 2014. Electro and Mary Jane may not make the final cut, but we're pretty certain the Osborn family is here to stay.
