What type of film often includes Easter eggs as a notable feature?

Animated films frequently incorporate Easter eggs as a notable feature. These Easter eggs are subtle, hidden references or inside jokes that creators embed within the film. They can include cameos of characters from other films, references to pop culture, or nods to the filmmakers' previous works. Animated films, particularly those produced by major studios like Pixar and Disney, are renowned for their playful use of Easter eggs, engaging audiences who enjoy spotting these treasures during multiple viewings.

While documentaries, romantic films, and action films can sometimes include Easter eggs, they are not as commonly recognized for this practice. Documentaries typically focus on factual content, romantic films emphasize narrative and character relationships without the playful hidden elements, and action films are generally more concerned with thrilling sequences and plot advancement. Thus, the tradition of embedding Easter eggs is most prominent and celebrated in animated films.
