What are some examples of allusions in movies?

Movies often use allusions to enhance storytelling and connect with audiences. For instance, in "The Shawshank Redemption," the protagonist references the story of the tortoise and the hare, symbolizing perseverance and hope. In "Pulp Fiction," the character Vincent Vega alludes to The Bible when discussing moral dilemmas, which adds depth to the narrative. Additionally, "The Lion King" includes an allusion to Shakespeare's "Hamlet" through themes of betrayal and revenge.
