Productions can be an expensive, emotional and time-consuming mess, and sometimes things get overlooked.

That said, theres no harm pointing and laughing when hilarious mistakes happen.

How many of these goofs did you notice?

By all accounts a good film, this coming-of-age tale was praised byRobert Ebertspecifically for its cinematography.

Which isfunny… mainly because the film shows us one of the people he is praising.

Good on you, unknown hero of cinema.

Or maybe its just a dude in a cowboy hat who wasnt supposed to be in the shot.

So, do we know whose cup it was?

Also, the filmhung a jacket on a cameraand hoped we wouldnt notice.

The solution was to drape a matching coat and tie onto the unit,almostmasking it in the shot.

What in the world happened while filming this scene that required the filmmakers to use two completely different cars?

How demanding could this cutaway shot possibly be?

Lets see if you could find the problem for yourself.

This is what gave us the terrifying raptors who pounced their way through our childhood nightmares.

See that part to the left of the raptor that looks like its tail?

Even when you notice it – this is still one of the best-looking films ever made!

Braveheart

Doing a period film presents a whole new library of opportunities to hilariously screw up.

Specifically, making sure that there isnt anything modern in your un-modern movie.

Therefore, It is simply a temporal impossibility that any of its characters would own a copy of 1993sMrs.

Honestly, thats not too unlike the plot ofRed Dragon,now that we think it aloud.

You know, like an extremely obvious coffee cup.

The scene, if youre curious, is when the ill-fated Ben Gardner sets out to go shark hunting.

Because when youre terrifyingly over-budget and behind schedule, every take counts!

And yet, it amazingly features an all-star spectrum ranging fromJon VoighttoIce Cube.

It is a gift.

A terrible, terrible gift.

It also has one of the funniest post-production cheats of any film.

It appears even water wants to escape this movie!

That is, unless the filmmakers forget to do it altogether.

The Avengers have been under close watch by fans, as Redditors have proven by spotting this next mistake…

While the CG certainly holds up, the featured technology inJurassic Parkis a whole other story.

For example, have you noticed this obvious imposter when Jedi Council arrives on Naboo?

For obvious reasons, we usually never see these stand ins at all.

Still, its a moment that feels downright surreal when devoid of context.

That isn’t the only timeFriendsslipped up.

You know, like if you accidentally revealed a gas canister during your big chariot race.

The moment is brief, but as undeniable as an accidental moment of nudity.

Only in this case its a much more family-friend undercarriage being exposed.

(And honestly, Sheldon and the gang would want it that way.)

For example, the shows explanation for the constantly-broken elevator doesnt quite add up.

When the show begins, we learn that the elevator has been mysteriously broken for two years.

Howard even tries to fix it in the Season 1 episode The Nerdvana Annihilation, but gives up instantly.

So why would he suddenly not remember how the elevator got destroyed, and attempt to fix it?

It is, 100%, a beautiful moment in time.

What you may not know, however, is just how beautiful this moment really is.

Because it turns out that this extras problems extended far beyond his upper half.

Or as he puts it I had paid three to four visits to the loo.

Its a beautiful thing to stand back from and admire.

Very often is this extended area an uncovered rock of crew members and exposed equipment.

One of the better examples is theX-Filesepisode Signs and Wonders.

While deep in an investigation, our protagonist agents walk and talk as they approach a person of interest.

If only they knew what the future held!

No better proof than his extremely 90sChasing Amy, andthe scenewhereJoey Lauren Adamsreconnects withBen Affleckafter a particularly dramatic monologue.

Filmed as a oner, its more complex than a lot of shots in Smiths films.

Its a familiar gaffe, but one that especially stands out considering the theme of loneliness in this moment.

Why did the numbers 4 and 5suddenly shiftto 19 and 20?

The only problem is that the handheld system very conspicuously lacks an actual game cartridge.

Avengers: Endgame

Thanks to Reddit, fans are already spotting problems with the newestAvengers: Endgame.

Seethe clipfor yourself and judge!

The jury is still very much out for this one.

Even the classiest of classics can have glaring and hilarious mistakes, it seems.

Is he the past form of Professor X?

Lets go with yes!

And instead of acting surprised, he preemptively blocked his ears to protect from the sound.

A good safety measure that makes for some terrible background acting!

One that goes deeper than any of us could even imagine?
