(at around 38 mins) In the film, Carol Danvers visits a bar called Pancho's, where she has flashbacks of her previous life on earth as a test pilot for the Air Force. Pancho's Bar, named after Pancho's Happy Bottom Riding Club, was a real bar/ranch/hotel, located near Edwards Air Force Base in the Mojave desert, in the 1940s. It was once home to many famous test pilots including Chuck Yeager, Bob Hoover, Jack Ridley, James Doolittle and Buzz Aldrin. It was owned by Pancho Barnes, a female aviation pioneer. She was an air-race pilot and Hollywood stunt pilot, and even replaced Amelia Earhart as a record holder for top speed. No doubt, the reference is a double-nod to Pancho Barnes's groundbreaking contributions to women in aviation and to her connection to the Edwards test pilot community.
Stan Lee passed away while the film was being edited. As a result, Marvel Studios put together the special opening logo to honor him.
The cutout character that Vers shoots in the Blockbuster store was originally supposed to be The Mask (1994), with Vers mistaking the green face for a Skrull, but the filmmakers couldn't secure the rights from Warner Bros., who owns the film's distribution rights and is also a rival company of Disney. Harry Tasker (Arnold Schwarzenegger) from True Lies (1994) was chosen instead.
(at around 30 mins) When Stan Lee makes his cameo, he is seen reading the script for Kevin Smith's Mallrats (1995) and reciting the line, "Trust me true believer". As revealed on Smith's YouTube page, Stan's health was in decline and he could not muster his trademark enthusiasm so the producers looped in Lee's unused audio from Mallrats.
Brie Larson is allergic to cats, so her scenes involving Goose were filmed with a puppet or computer-generated VFX.
Kelly Sue DeConnick: (at around 33 mins) Captain Marvel writer (from 2012-2015), as a bystander in the train station who looks at Marvel.
