What's a movie plot hole that still bothers you years later?

What mind-bending plot holes from movies still bother you years later?

For me its Interstellar. The entire mission depends on the wormhole that future humans supposedly created. But how could they exist to create it if humanity was on the brink of extinction and needed the wormhole to survive in the first place? It's like a chicken-and-egg problem on a cosmic scale. Without the wormhole, humanity dies out. But if humanity dies out, there are no future humans to create the wormhole.
