A few months ago I read that Paul Giamatti was interested in playing the Rhino, a member of Spider-Man’s rogues gallery. At the time I recall thinking that that was some of the most awesome casting that I have heard in a long while–mainly because he actually looks like the character–though I didn’t think much of it because Jamie Foxx had already been cast as Electro in the sequel.
And as much as I would like to have seen Giamatti in the role, I didn’t want to see another ‘Spider-Man 2’ scenario, where you had villains thrown together in perhaps the most inorganic manner possible without the background that would make such an effort successful.
The only thing that reassures me somewhat is that the Rhino and Electro actually have banned together against Spider-Man in the comics, which at least means that it won’t feel as left-fieldish as Sandman teaming up with Venom (though admittedly the problem with that lies more with the writing than the characters because, besides the fact that better writers could have pulled it off, many of the people that will see the film will probably have no idea of the history between the two characters).
This leads me to believe that the filmmakers are building up toward unveiling The Sinister Six (The Vulture, Electro, Mysterio, and Kraven the Hunter, or some variation thereof), which would be all sorts of cool.
