Charlize Theron's latest movie is wowing viewers thanks to its fantastic fight sequences and backstory that goes back centuries. And it turns out the movie has just scratched the surface on what can be explored.

"The Old Guard" is based on a comic book by Leandro Fernández and Greg Rucka (Rucka also wrote the movie's screenplay). It chronicles the lives of Andromache the Scythian, known as Andy (Theron), and her team of immortals. For centuries, they have been fighting battles and saving lives.

The comics, through Image Comics, are made up of two five-issue series: "The Old Guard" (2017) and "The Old Guard: Force Multiplied," which concludes Wednesday when its fifth part is released.

The movie's director, Gina Prince-Bythewood, does a fantastic job giving us an entry into this bloody world. And thanks to Rucka as the screenwriter, it's very true to the source material.

Still, there are some major tweaks and omissions. Here are the 5 biggest differences between the movie and the comics.
