The Amazing Spider-Man 2 trailer is here, and it looks pretty amazing. Its jam-packed full of huge teasers. Most of which we expected. But the eagled-eyed viewers over at Screent Rant have pointed out possibly the trailer's coolest Easter egg. And that is the OsCorp harnesses for Vulture and Doctor Octopus inside the OsCorp lab. Watch the trailer again and see if you can spot them (they are seen at the 1:14 mark).

The Amazing Spider-Man 2 Vulture and Doctor Octopus

The trailer goes onto confirm that we will be getting three villains this time out, Rhino (Paul Giamatti), Electro (Andrew Garfield) and Peter Parker's old friend Harry Osborn (Dane DeHaan), who will be transformed into the Green Goblin during an experiment at OsCorp.

We've known for a while that this movie was leading into a Sinister 6 storyline that will be further explored in The Amazing Spider-Man 3 and The Amazing Spider-Man 4. Both Vulture and Doctor Octopus have been former members of the Sinister 6. And as Screent Rant points out, Colm Feore was at one point listed on IMDB as Vulture's alter ego Adrian Tombs, though that has since been removed. Director Marc Webb even posted this picture of the actor, who has that Vulture look, working at the Ravencroft Institute for Criminals.
