Marvel and DC have produced / will produce 44 superhero films during this decade (based on current information; more could be announced).
Of the 44 films, only two are led by women and only two are led by a person of color (and that's counting Big Hero 6).
44 superhero films in 10 years, and 40 of them are led by straight white men.

Though if a man of Hawaiian descent counts as a person of color, then Aquaman is also led by a POC and the straight-white-man count falls to 39.
Either way, the point remains the same. Superhero films are overwhelmingly limited in terms of diversity, which is annoying, problematic, and a bit offensive.
