The latest DC comic book character to be brought into the live action fold is Courtney Whittemore, also known as Stargirl. The character headlines her own show on DC Universe, which is making the move to the CW for its second season. Early episodes of the show were chock full of Easter eggs that actually became devices to move the plot forward as the first season progressed.
Throughout the first season of the series, however, there are also plenty of Easter eggs snuck into the show for the audience to find that didn't have major reveals. Some of them were nods to the comics in which Stargirl and associated characters originated, while other Easter eggs were a little more personal.
American Action Movers
When Courtney and her mom make the move to Blue Valley, they do so with the help of a moving company. That company is a double Easter egg.
American Action Movers is a nod to Action Comics - the logo even has the same font. That's the original series in which Superman made his debut. The moving truck Easter egg was also lifted right out of the comics. American Action Movers appeared in Stars And S.T.R.I.P.E.
Doctor Weerd
Courtney is the first character to discover that Pat has a secret past as the sidekick to a superhero. When she makes the discovery, it's by going through a trunk of his things, which includes some old newspaper clippings.
One of those newspaper articles highlights that the Star-Spangled Kid and Stripesy battled a villain named Doctor Weerd. Though the character doesn't get discussed in the show outside of the article, he's right out of the comics. He was a university professor who created a formula that turned him into an ogre.
Forgotten Communities
In the third episode of the series, Jordan makes a speech to his American Dream employees. Over the course of the speech, he makes a comment about some "forgotten communities." They are Littleville and Hatton Corners. Those might seem like throwaway names, but they're not.
Both towns exist in DC Comics. Littleville made its comic book debut in the 1960s in the House of Mystery series. Hatton Corners also made its debut in the '60s, but in an issue of The Brave And The Bold. It's the city where Robin, Kid Flash, and Aqualad first team up, creating a path to the Teen Titans.
Wildcat's Wiki Page
As Courtney begins to make her own team, she starts looking up the superheroes who came before her. Eagle-eyed viewers will spot a lot of details in the Wikipedia entry she reads for Wildcat.
Among those details are some comic book Easter eggs. The entry mentions Wildcat' fight against the Manfredi drug cartel. Wildcat actually took on Manfredi in the comics with the help of Batman. Likewise, the entry mentions that Wildcat had a rivalry with the villain Tigress. In the comics, that rivalry goes all the way back to the days when she was still calling herself Huntress instead.
1941 And 1999
Fans paying attention to prices and codes in the series will see these two numbers pop up an awful lot. That's because they hold special meaning in the comics.
1941 is the year the Justice Society is founded - and also the year the Star-Spangled Kid and Stripesy debuted in comics, created by Jerry Siegel, who also gets a shout out in an address. 1999 is the year Courtney Whittemore, who would become Stargirl, of course, debuted in DC Comics.
Calvin College
Rick spends a lot of time in the series trying to crack the code in his father's old journal. While working on it in episode six, he makes mention of a school named Calvin College. Fans of the Atom might recognize the name.
The university made its debut in All American Comics with the Atom. Then, the Atom was Al Pratt, and most of his stories took place on the school's campus, though the school hasn't been seen much in modern comics.
Firebrand And Bannerman Chemical
These particular companies are name checked by Icicle in the eighth episode of the series when he's murdering Ed Reilly. Both of those names come right out of the comics.
Firebrand, however, isn't a company in the comics, but the name of a superhero. He also happens to be the father of Ed Reilly. Bannerman Chemical, on the other hand, is a company. It's the company where Rex Tyler worked and created the formula to become Hourman.
Soda Cola
Television shows and movies frequently use nonexistent or generic names instead of using brands for products. Some fans might have thought "soda cola" would be a case of just that, but it actually exists as a brand in DC comics.
It's seen in Stargirl when Henry Jr. practices his newfound powers on a can. In the comics, it's been seen all over the place. The brand even acted as a sponsor for Booster Gold at one point.
Movie Posters
Blue Valley has a single movie theater in town. Outside of the theater, the walls are full of movie posters in multiple episodes, just like what we would see in the real world. The difference, of course, is that the movies in Stargirl's world depict ones that don't exist in the real world. That's because they're inspired by some DC comic book characters.
One poster, for example, is for The Rita Farr Story. Rita Farr is also known as Elastigirl and is one of the main characters of Doom Patrol. Another is for Prez, which is the story of the first teenage President, which is also the subject of a DC comic book series.
Courtney Johns
The final episode of the season is dedicated to Courtney Johns, the person who is the namesake for the titular Stargirl. Sister of comic book heavyweight Geoff Johns, Courtney Johns was killed in a car accident in 1996. Three years later, he created Courtney Whittemore in her honor.
The real life Courtney is featured in the series. Her photo can be seen right in the middle of Courtney Whittemore's bulletin board at the start of the show. She's the girl sitting next to the title character on a bench. That photo remains on Courtney's board throughout the entire first season, making both Courtneys a part of the show.
