Marvel snuck in a slew of Easter eggs in Avengers: Endgame, but there was one hidden clue that most fans completely missed. The Easter egg in question was a reference to one of the filming locations, something that only the locals probably noticed. Here’s a look at one of Endgame’s most bizarre Easter eggs, plus a list of some of the film’s other hidden gems.

Marvel gives this country its own Easter egg

The Easter egg most Marvel fans missed came during a scene with Thor (Chris Hemsworth) in Norway. Bruce Banner (Mark Ruffalo) and Rocket (Bradley Cooper) were trying to convince Thor to help them pull off the time heist.

In the background of one of the shots inside Thor’s home is a soda bottle with the name Irn-Bru. According to We Got This Covered, the drink is very popular in Scotland, which is where the scenes were actually filmed.

The fact that the bottle was clearly displayed is a sign that Marvel intentionally put it into the Avengers: Endgame scene. People from Scotland were quick to notice the drink, which is reportedly used as a cure for hangovers.

The drink, which is pronounced “iron brew,” actually sells better than Coca-Cola in Scotland and is commonly called the country’s “other national drink.”

What’s even more interesting is that the beverage actually contains a tiny amount of iron, which is where it gets its name.

The most obscure Easter eggs of ‘Avengers: Endgame’

Speaking of Easter eggs most fans completely missed, there was actually a shot in Endgame that featured Howard the Duck. The character showed up in the final battle scene with Thanos (Josh Brolin) and can be spotted as the camera pans over Wasp (Evangeline Lilly).

The creator of Thanos, Jim Starlin, also enjoyed a brief cameo in Avengers: Endgame. Starlin is featured in the scene where Captain America (Chris Evans) is talking to a support group. For reference, he is the bald guy sitting next to director Joe Russo.

Another Easter egg many fans missed came in the form of a character’s name on The Vanished Memorial. When Scott Lang (Paul Rudd) was looking for his daughter’s name on the wall, the camera panned across the name of Roberto da Costa, a member of the X-Men called Sunspot.

Marvel is expected to introduce the X-Men now that it owns the rights from Fox. We do not know which mutants will appear in the MCU, but it looks like Sunspot might be on that list.

Captain America enjoys a few Easter eggs

Avengers: Endgame also featured a few hidden gems related to Captain America, who retired at the end of the film. This includes Cap saying “Hail Hydra” in a bid to retrieve the Mind Stone from some Hydra agents.

The reference is a callback to a story in the comics called Secret Empire. In that storyline, it was revealed that Cap was actually a sleeper agent with Hydra, a move that did not go over well with fans. That story has since been ditched, which is why the reference in Avengers: Endgame is so funny.

There was also an Easter egg when Sam Wilson, a.k.a. The Falcon (Anthony Mackie), radioed in to fight Thanos alongside Cap and the rest of the Avengers. In a pivotal moment in the battle, Falcon tells Cap, “On your left,” which is a reference to a scene in Captain America: The Winter Soldier.

In that movie, Sam is shown running in Washington while Cap keeps lapping him, saying “On your left,” as he runs by.

Here are all the Easter eggs related to Iron Man

Captain America wasn’t the only Avenger who got multiple Easter eggs. Tony Stark (Robert Downey Jr.) also got some hidden gems throughout the movie.

This includes an appearance by the original Jarvis when Tony and Cap traveled to the 1970s to secure the Space Stone. Jarvis shows up to drive Tony’s father, Howard Stark, out of the base.

Iron Man’s other Easter egg is related to his famous line, “I love you 3000.” Although the line was meant to be a cute moment between Tony and his daughter, it has greater significance beyond the scene.

A fan went back and added up all the run-times of the Marvel films leading up to Avengers: Endgame, and the end result is close to 3000 minutes.
