Just like in the first film, Brie Larson had to use a stunt double in scenes where Carol is in the same room with Goose, due to her being severely allergic to cats in real life.
The comic book version of Monica Rambeau was code named Captain Marvel, Photon, Pulsar, and Spectrum, among others, in various iterations. Photon, Pulsar, and Spectrum are all among the code names Kamala suggests for Monica in this movie.
Monica initially calls Dar-Benn's Accuser weapon a "hammer", before Carol corrects her by saying it's "the Universal Weapon". Kamala says she expected something cooler like "the Cosmi-Rod." In the comics, the terms are both used for the Accusers weapons.
The hammer is similar to the Cosmi-Rod that Ronan the Accuser used in Guardians of the Galaxy, and Kamala refers to Dar-Benn's weapon by that name. However, Carol Danvers correctly calls it a Universal Weapon, which is the original name of the weapon in the comics.
At 1 hour and 45 minutes, this is the shortest MCU film, surpassing The Incredible Hulk (2008) and Thor: The Dark World (2013), at 1 hour and 52 minutes each.
