Re: Things you noticed after multiple viewings on DVD / BluRay.
I noticed the stock exchange motorcycle chase was filmed in downtown Los Angeles, I recognized the streets and birds eye view of the buildings, I even know what alley they filmed when The Bat first pops up escaping the Gotham police.
A few of the Marvel Superheroes are somewhat niche characters that aren't extremely versatile, thus they don't have a lot of longevity potential. For example, Namor is a water guy, Silver Surfer is a space guy, Dr. Strange is a magic guy, and so on.
