I just stumbled upon these images of Andrew Garfield and Paul Giamatti taken during filming of The Amazing Spider-Man 2. The photos show a fight scene between Spidey and a villain called the Rhino. The baddie will be a CGI construct, so Giamatti is lashed into the practical elements of the suit that will be gussied up later by the whiz kidz with the fancy computers.
According to a witness, the battle scene sees Spider-Man grab a megaphone to taunt Rhino as “a mechanized hippopotamus.” (That sounds like a very in-character taunt to me!) The spider-sequel opens May 2, 2014.
