Directed by: Sam Raimi

Character mistake: In the start of the film, the sticker on Peter's head for his work misspells the word Bleecker Street on it.
Continuity mistake: Peter back flips off his moped to avoid the car racing at him. There were cop cars and other vehicles behind that car when Peter jumps, but when he lands only one cop car goes past in the lane next to him and the lane he's standing in is then clear of traffic as he talks to some kids.
Factual error: Considering the brightness of the fusion process, Dr. Octavius has to wear special goggles to be able to see it. Yet no one else in the room is wearing such goggles or seem hurt by watching the whole process, just as at the end of the movie. When welding something, no one can look at the arc that's created, as it would hurt his eyes and burn his retina; presumably, the fusion process would be brighter and more powerful than that, and so should have some kind of damaging effect on everyone's eyesight (except Spider Man's, maybe).
Mr. Ditkovich: If promises were crackers, my daughter would be fat.
Answer: Unless there is is a deleted scene to shed light on the issue, then it's not really addressed in the movie. It's possible that Doc Ock and Harry had a second meeting that took place off-screen in which Ock revealed to Harry where his hideout was, but as there's nothing really to go on, it's anyone's guess and it's reasonable to consider it a plot hole.
