In most of the spiderman films, the viewer knows that peter parker is actually a superhero, but his character manages to hide that from those around him. his bedroom has posters, décor, and items typical for a normal guy his age. but once he puts on that spiderman costume, he becomes the anonymous hero his town depends on to fight crime.
spiderman illustrates the technique of dramatic irony because
the audience learns a lot about peter from the items in his bedroom
the spiderman suit creates suspense and hints at future events
the audience knows something that the film characters don't know
the spiderman suit is a plot device that brings characters together
