In its first trailer, The Amazing Spider-Man 2 was willing to give fans a peek at what might be in store for the third film, but it's still keeping a few secrets.  We don't have official confirmation on who Felicity Jones is playing (although she may have let it slip) or on B.J. Novak's role.  But in a recent interview, Novak told The Huffington Post:

I'm in a couple of scenes. Yeah, I was never told whether or not I could say. I can say that I work at Oscorp. And I am someone from the comic books, someone from the original. So, yeah, I'm somebody. I wouldn't say I'm pivotal, but I'm not an extra, either.

If that's the case and if the viral campaign lines up, I'd put my money on Alistair Smythe, son of Spider-Slayer creator Spencer Smythe, who also works at OsCorp.  Whoever Novak is playing, we'll probably find out before the film opens on May 2, 2014.
