Movies can get away with a lot when the story is entertaining enough. Audiences will accept impossible coincidences, questionable decisions, and elaborate plans that would fall apart the second anyone stopped to think. But sometimes a movie makes a mistake so glaring that it becomes impossible to ignore once you notice it. A character forgets something they knew moments earlier, a supposedly brilliant plan depends on everyone acting foolishly, or a major problem could have been solved with one simple question. These plot holes have left viewers scratching their heads, wondering how nobody caught them before the movie hit theaters.IMDbHarry Potter and the Prisoner of Azkaban (2004): Time Travel Could Solve EverythingHermione uses a Time-Turner to attend multiple classes, and later the device helps save Sirius Black and Buckbeak. Naturally, this raises a huge question: why isn’t time travel used to prevent other disasters throughout the wizarding world?cnx.cmd.push(function() {cnx({playerId: "106e33c0-3911-473c-b599-b1426db57530",}).render("0270c398a82f44f49c23c16122516796");});IMDbHome Alone (1990): Why Doesn’t Kevin Call the Police?Kevin realizes his family has left him home alone, then spends much of the movie preparing elaborate traps for burglars. He’s resourceful enough to build an entire defensive obstacle course, but the obvious solution is to call the police and explain what’s happening.IMDbJurassic Park (1993): The T. Rex’s Magical CliffDuring the famous T. rex attack, the ground behind the vehicles suddenly becomes a massive cliff. Moments earlier, the area appeared relatively flat, and the movie never properly explains where that enormous drop came from.IMDbThe Little Mermaid (1989): Ariel Can WriteAriel loses her voice after making a deal with Ursula, which creates the central problem of her romance with Eric. But Ariel can write. She could theoretically explain who she is, why she cannot speak, and what happened to her voice without needing to rely on guesswork and awkward gestures.IMDbSigns (2002): Aliens Invade a Planet Covered in WaterThe aliens in Signs are supposedly vulnerable to water, yet they invade Earth, a planet covered in oceans, lakes, rivers, and rain. They can apparently travel between planets but somehow overlook one of Earth’s most obvious features.IMDbThe Dark Knight Rises (2012): Batman Gets Back to GothamBruce Wayne escapes from a remote prison, apparently without money, equipment, or any obvious means of transportation. Gotham is under siege, surrounded by a military blockade, and cut off from the outside world. Yet Batman somehow makes it back in time to save the city.IMDbThe Dark Knight (2008): Batman’s Fingerprint BulletBatman reconstructs a bullet by firing it into a wall and recovering the fragments to identify a suspect through a fingerprint. The problem is that a fired bullet generally doesn’t retain a clean fingerprint in the way the scene suggests.IMDbStar Wars: The Last Jedi (2017): The Hyperspace CollisionThe Resistance ship Raddus jumps into hyperspace and slices through the First Order fleet, destroying enormous ships in the process. If hyperspace can be weaponized like that, why hasn’t anyone routinely used unmanned ships or cheap vessels as interstellar missiles?IMDbIndependence Day (1996): The Convenient Alien Computer VirusDavid Levinson defeats the alien invasion’s computer systems by uploading a virus from a human laptop into an extraterrestrial mothership. The plan depends on the aliens using technology compatible enough with Earth’s computers for a virus to work.IMDbThe Avengers (2012): Why Doesn’t Thor Just Take Loki Away?Once the Avengers capture Loki, they place him aboard the Helicarrier, where he proceeds to manipulate the team and trigger a catastrophic chain of events. Thor is powerful enough to transport Loki away using the Bifrost, at least under the right circumstances, so keeping him aboard a vulnerable flying headquarters seems like an unnecessary risk.IMDbBack to the Future (1985): Marty’s Existence Depends on a PhotographAs Marty McFly’s parents become less likely to fall in love, his siblings begin disappearing from a photograph, followed by Marty himself. Yet the movie’s timeline suggests that major changes to the past can affect the present almost immediately, while Marty continues existing long enough to fix everything.IMDbThe Wizard of Oz (1939): The Ruby Slippers Could Have Solved EverythingDorothy spends much of the movie traveling through Oz, facing dangerous situations while trying to find a way home. At the end, Glinda explains that Dorothy could have used the ruby slippers to return to Kansas all along.IMDbAvengers: Endgame (2019): The Rules of Time Travel Get ConfusingThe Avengers travel through time to collect the Infinity Stones, with Bruce Banner explaining that changing the past doesn’t simply rewrite their present.

That’s a compelling weakness for an immortal sea captain, but the heart becomes a portable object that multiple characters can steal, hide, or carry around.The post 15 Movie Plot Holes Big Enough to Fit Your Ram 1500 appeared first on Den of Geek.
