It's official: JAMIE FOXX will play the villain Electro in the next "Spider-Man" movie.

Jamie says, quote, "I met with the director, Mark Webb, I met with Andrew Garfield, and we talked.

"I think Electro will be an exciting character to play because he's a . . . genius electrician-type person, and he gets the short end of the stick from the whole world, and the next thing you know he turns it on."

Meanwhile, DANE DEHAAN . . . from the underrated 2012 sci-fi flick "Chronicle" . . . will play Harry Osborn.  He's Peter Parker's best friend and the son of the Green Goblin.  JAMES FRANCO played him in the original trilogy.
