Other mistake: Spider-Man is shown web-slinging past several glass buildings, but he does not cast a reflection in any of them. (00:00:10)
Continuity mistake: When Peter and Debra are approaching Dr. Connors' office, the nameplate on his door misspells his name as "DR. CURT CONNeRS". After they have entered the lab, the nameplate is shown to have the correct spelling. (00:06:10)
Deliberate mistake: When the sewer worker is trying to escape the Lizard, the fast lanes in both directions of traffic are visibly clear for several blocks, which is extremely unlikely in downtown New York. (00:01:10)
Answer: In the comics, Hobgoblin's true identity was kept a mystery for a long time intentionally and while many fans deduced it was Kingsley, and creator Roger Stern was leaning that way, Stern left the series in 1984. In 1987 Hobgoblin's identity was revealed to be Ned Leeds and then Macendale became Hobgoblin. It wasn't until 1997 that Sterns wrote the mini-series "Hobgoblin Lives" and retconned Kingsley as the original Hobgoblin.
