Movie Mistakes So Dumb You’ll Wonder How You Missed Them

Movies are awesome and awesome movies are even better, but sometimes even the biggest Hollywood blockbusters are hiding some seriously goofy fails. Whether it’s a tech flub, an editing oopsie, or a time-traveling guitar that shouldn’t even exist yet, these mistakes are hiding in plain sight, and once you see them, you can’t unsee them.

Here are some movie mistakes that’ll make you do a double-take.

1. Back to the Future (1985)

Remember Marty McFly’s epic rock’n’roll performance? He had a sick Gibson ES-345, which is awesome, except the ES-345 didn’t exist until 1958, and this scene is set in 1955. That’s right, Marty time-traveled with an instrument from the future that technically hadn’t been invented yet. Maybe Doc Brown also packed a music catalog for the ride. Ironically, the song he plays—

Chuck Berry’s “Johnny B. Goode”—also hadn’t been recorded yet, so Marty might have invented rock’n’roll by accident, too.

2. Pulp Fiction (1994)

Christopher Walken’s intense monologue about a gold watch is one of the film’s most memorable moments. But the watch itself has other plans. As the camera zooms in on it, the time shown doesn’t match what Walken’s character just said. Continuity much? Also, that gold watch has seen some stuff. According to Walken’s character, it was hidden in, uh, “you know where.” Let’s just say the time’s wrong and it needs disinfecting.

3. Charlie’s Angels (2000)

Near the end of the movie, Sam Rockwell is supposed to be flying a helicopter, but someone forgot to fully key out the green screen behind him in post. So, instead of sky or cityscape, we get a surreal moment of Rockwell against a weird, glowing green void. Honestly, it looks like he’s hovering through a radioactive smoothie. But who cares about realism when you’ve got Cameron Diaz backflipping off rooftops?

4. Jurassic Park (1993)

The T-Rex scene is legendary. First, the giant lizard breaks out of the paddock and steps over the goat’s former snack location. But later, Dr. Grant and the kids rappel down a massive cliff from the same spot the T-Rex just walked out of. Like, huh? Was the fence built on a floating platform? Despite Jurassic Park making a billion dollars, nobody can explain this magical disappearing terrain.
