My favorite movie is Spiderman, it starts with Spider-Man as Tobey Maguire and Green goblin as Willem Dafoe, the director is Sam Raimi. The movie is about Peter Parker (Spider-Man), born a long time ago in the Queens borough of New York, it begins when he is bitten by a genetically modified spider, Peter is a shy high school student who gains incredible spider-like abilities. The next morning, Peter wakes up to find that his physical form has changed, gaining strength and agility, and his vision problems have disappeared. 

At the same time, Harry's father, Norman Osborn, is the victim of a chemical accident that has increased his strength, but he goes mad and becomes the Green Goblin, a demonic creature that threatens the city. A fight ensues between him and Spider-Man, in the end Spider-Man wins and saves the city.

I like this movie because you get to see how he creates his suit and also because he fights villains.
