In the two-and-a-half-minute trailer, voiceover by Peter Parker (Andrew Garfield) reveals that the biggest struggle in his life – bigger even than dating the daughter of the police chief on his tail – is unraveling the mystery of his parents' disappearance. New footage breezes past his bitten-by-a-radioactive-spider origin story to showcase Spidey's sense of humor -- on display in a scene where he jokingly cowers after a thief pulls a knife on him.

As Gwen Stacy (Emma Stone) points out that her father, Captain Stacy (Denis Leary), has 500 men looking for Spider-Man, Parker squares off against Dr. Curt Connors (Rhys Ifans), using the skyscrapers of New York City as his jungle gym.

The Amazing Spider-Man opens nationwide in theaters on July 3, 2012.
