IGN has a story up that shows a locker with the number 14, from a set photo tweeted by Marc Webb with the hashtag #happybirthday. Knowing Dane Dehaan has been cast as Harry Osborn fans have already started freaking out about the picture and drawing conclusions from it.
In the Ultimate Spiderman comics Eddie Brock and Peter Parker find the Venom suit in a locker with the same number. February 6th is Dehaans birthday and Josh Trank, who directed Chronicle, is set to direct the Venom stand alone movie. All signs point to Dehaan being Venom outside of him being cast as Harry Osborn. I think Dehaan, the actor, would make a great Venom. However I'm tired of the skinny Venom, didn't like it in Spidey 3, don't like the idea of it now.
