Often in the narrartives in the openings of superhero movies we find out about the origin story or how the superhero gains their powers. This is obviously a pivotal point for a superhero movie, as the whole film is likely to revolving around them as the hero. This will be interesting for both a fan of the movie and will also create understanding for somone who is new to the series.
For this reason quite a lot of the narratives of these films are quite charecterer based. For example, where Peter Parker gains his powers is revolved around him as a charecter, in his 'normal' everyday life. We see him and what he does in his normal life, as a photographer,
I think that this is something that we should definately focus on in the opening, as it is something that will be able to achieve well.
