Sure is! 'Eternals' originated from Marvel Comics. The movie takes inspiration and elements from the comic book series to create its story and characters.
The Eternals in the comics are not robots. They have complex backstories and powers that distinguish them from mechanical entities. Their existence is tied to cosmic forces and ancient histories.
Overall, 'Eternals' has some differences from the comics. Some characters' powers and backstories were modified, and the plot took some creative turns. But it still retains some core elements.
