Which of the following best defines an "Easter egg"?

An "Easter egg" refers to a hidden message, image, or feature in a film, video game, or other forms of media, often serving as a nod to pop culture or referencing other works. The correct answer highlights that these Easter eggs are intentionally placed by creators for audiences to discover, creating an engaging experience that rewards viewer awareness and familiarity with cultural phenomena. This can include subtle visual references, cameos, or callbacks to previous works, which enrich the viewing experience and foster a sense of community among fans who share insights about these hidden gems.

In contrast, a recurring theme in a film describes central motifs that unfold throughout the storyline, while a crucial plot twist fundamentally alters the audience's understanding of the narrative. Special effects, on the other hand, involve various techniques to create illusions for the viewer but do not necessarily involve hidden messages or references.
