From IFM: "There are four villains this time, Venom, Sandman, and Green Goblin and when is the fourth going to be revealed?
(Avi) Arad: Right we have four villains. Pretty soon [we’ll reveal the fourth villain] I believe. Maybe around Comic Con we’ll reveal something and the madness will begin."
In related news, Mr. Arad recently QUIT HIS JOB at Marvel! Didn’t see that coming!
Also, AICN has some SM3 on-set snapshots the see Spidey swingin’ with Ron Howard’s daughter.
