The 2019 film “Captain Marvel” – a superhero origin story about the journey of fighter pilot Carol Danvers (Brie Larson) to adopt the mantle of the titular, cosmic-energy-enhanced champion – broke ground as the first woman-led feature in the Marvel Cinematic Universe. (Of course, it arrived two years after DC Comics’ invigorating “Wonder Woman” beat it to the punch, so to speak.) A new sequel, “The Marvels,” ups the representation ante by teaming Carol with two sidekicks: Pakistani American teenager Kamala Khan (Iman Vellani), already known to franchise fans as the protagonist of the Disney Plus spinoff “Ms. Marvel,” about a Jersey City crime fighter who idolizes Carol’s alter ego, and Monica Rambeau (Teyonah Parris), a Black astronaut who has somehow morphed from a little girl in “Captain Marvel” to a 30-something woman, while Carol, whom she calls her “aunt,” looks exactly the same.
