#10 - 'Avengers: Endgame'
​(Tony Stark Dies a Hero)

Mass Spoiled By: The release of the second 'Spider-Man: Far from Home' trailer, that reveals his death.

Why It's Okay: Well, for starters, the Russo brothers said it was okay. But to add onto that, it's just the fact that these Marvel movies are carrying on, very clearly with his death as the jumping off point. There are other big reveals throughout this movie, but Stark is the "big deal" here, especially considering how he dies, along with the fact that it all started 11 years prior with him. 'Endgame' is where Stark comes full-circle.

​Stark's passing also just plays a big part in 'Far from Home', where there's a "passing of the torch" from Stark to Parker as the face of the MCU. The trailer basically just shows you Stark is gone now, so for as big of a spoiler as it seems to be, the MCU has given permission to make this spoiler common knowledge. It's still fresh, however, so it's not exactly high on the list.

#09 - 'Fight Club'
​(Tyler Durden Isn't Real)

Mass Spoiled By: Age which has created a very generous cult following, combined with word of mouth and a lot of internet lists about "best twists/reveals of all time".

Why It's Okay: To be perfectly honest, this is still one I tend to tiptoe around for newcomers because it IS a cool twist. The big reveal wasn't spoiled for me before seeing it, making it all that much more impactful. I was able to go through this one a second time and appreciate it more, picking out little things here and there along the way - that's just how one needs to see this movie.

Unfortunately for it, it's over 20 years old now, and the twist has ended up all over the internet. It's reasonable to say at this point that this one is common knowledge for common movie goers, but I feel like there's still something to keep hidden here for people who aren't quite as into movies. So it's still a bit low on the list. It's a pretty cool movie either way though, and knowing the end result almost makes watching it more fun.

#08 - 'The Sixth Sense'
​(Bruce Willis is a Ghost)

Mass Spoiled By: Age combined with word of mouth, '50 First Dates', and being one of the all time best-known Hollywood twists, punctuating Shyamalan's signature directorial "move"

Why It's Okay: As mentioned above, it's just plain too well-known. It really is one of the most famous movie twists of all time, and anyone who knows who Shyamalan is as a director, can attribute his famous "twist endings" to this movie starting it all. It is the quintessential Shyamalan twist ending to see. It's still heavily regarded as his best film, and that reveal is exactly why.

If you go in blindly, I think this is still a solid, and effective reveal. Much like with 'Fight Club', it makes you go through the movie a second time, and it does a great job at playing to an audience's ignorance, including my own. Sure, You have all those people who claim to have known the whole time, but it's never something you wanna hear. It just brings such a good twist down. This was one where being clueless made it more interesting.

#07 - 'Harry Potter and the Half-Blood Prince
​(Snape Kills Dumbledore)

Mass Spoiled By: Some asshole standing in line for the 6th book upon its release, the Internet, word of mouth, reading the book prior to seeing the movie.

Why It's Okay: The 'Half-Blood Prince' movie was released in 2009, thus officially making this particular big reveal a few years old as it was with the book being released in 2005. This particular spoiler was known to the masses very quickly, becoming something of a meme at the time. It was actually sort of difficult to avoid.

Using myself as an example, a friend spoiled for me that Dumbledore died, but in fairness, didn't reveal how. Then I just stumbled on it all by myself while surfing the net, going through eBaum's World. It was a complete accident! Anyway, nowadays, this is just out there as common knowledge, and if you don't know it, you either don't care at all as it is, or you've been under a rock for a solid 10+ years.

#06 - 'Psycho'
(Norman Bates is His Mother)

Mass Spoiled By: Age, word of mouth, being one of the first, legendary great film twists, 'Bates Motel', 'Hitchcock'.

Why It's Okay: 'Psycho' is widely regarded as one of the greatest thrillers of all time, and pretty well holds claim to the all-out beginning of slasher films. It has aged extremely well, it's potentially Hitchcock's biggest and best film (depending on who you ask), and it's just in the history books at this point as far as film making goes in general.

'Bates Motel' has also become a very popular series with people, running a full five seasons, and opening up the potential for major 'Psycho' spoilers during that time. There's also a movie, 'Hitchcock' (featuring Anthony Hopkins as the titular character) which profiles this film in a big way. Above all else, however, this is just a famous ending nowadays. Most fans of thrillers know it, and fans of Hitchcock absolutely know it. It's simply "old news" now.

#05 - 'Soylent Green'
(Soylent Green is People)

Mass Spoiled By: Age, memes, TV references

Why It's Okay: This is a fine example of a movie I have never actually seen before, but here it is on the list. Throughout the years, I have seen a whole whack of cartoons, TV shows, and sci-fi comedies that in some way, shape of form parody this film. Without seeing it, and without even looking things up, I can still give the rough plot away that a dystopian society thrives on this wonderful new food called "Soylent Green", which, in the end, ends up being, essentially, processed human being.

On top of that, since YouTube has been a thing, one has been able to find the clip of Charlton Heston yelling "SOYLENT GREEN IS PEOPLE!". It has become a gif, a meme, and just one of those clips that looks hilarious in its melodrama when its out of context. I probably should watch it one day, but honestly, this one was spoiled for me since childhood.

#04 - 'Citizen Kane'
(Rosebud is a Sled)

Mass Spoiled By: Age, many, many parodies and overall fame of the twist ending

Why It's Okay: Funny story, but I've thought this was common knowledge since I was a kid. Both 'The Simpsons' and 'Tiny Toons' referenced it, and every so often you'd hear talk of Rosebud being a sled on movies and sitcoms. I actually remember spoiling this for my parents when they were watching it for the first time (well, at least my Dad). I was so confused by that because I thought it was well-known at that point.

In any case, it goes without saying that 'Citizen Kane' is toted as one of the greatest films of all time, if not the greatest. It really is a fascinating movie, even knowing the twist, and I do recommend checking it out. But back in the 90s and early 2000s, knowledge of this twist ending was everywhere, so if this does end up spoiling things for you, it only means I'm the first to do it.

#03 - 'The Planet of the Apes'
(It was Earth All Along)

Mass Spoiled By: Age, film and TV references, the semi-buried Statue of Liberty is now iconic.

Why It's Okay: 'The Planet of the Apes' has been a sci-fi favorite for people for decades now. It was remade in 2001 with Tim Burton's direction, and remade again with a fantastic trilogy with 'Rise', 'Dawn' and 'War' (seriously one of the best trilogies out there if you ask me). The twist ending of this is famous enough that the recent trilogy actually serves as a prequel to the 1968 classic.

The famous "damn you all to Hell" ending has been parodied again and again over the years, and the Statue of Liberty that reveals the planet having been Earth all along is iconic now. Hell, Lego even boasts a kit from their 'LEGO Movie 2' collection that depicts the same basic image. It has been a long-standing, well-known reveal for half a century now.

#02 - 'The Wizard of Oz'
(The Wizard is Just a Man)

Mass Spoiled By: Age, film and TV references, one of the most watched films of all time

Why It's Okay: Most everyone has seen or read some incarnation of this story by this point. With the whole point of the film being that things like smarts, heart and courage are in us the whole time, one might be able to give this story real credit for starting one of the best-known family movie cliches. Whenever I hear something along the lines of "Don't you see? You had the power all along!" I think about this ending. The Wizard is revealed to be just some guy, so he ends up being the real incarnation of the whole lesson.

The film was a big enough deal when it was released 80+ years ago. Since then, there have been various adaptations, and it has been featured as a TV movie about a million times. This is right up there with common fairytales nowadays as far as how knowledgeable the general public is about it. It seems most people, even without seeing this, know how it ends.

#01 - 'Star Wars: The Empire Strikes Back'
(Darth Vader is Luke's Father)

Mass Spoiled By: Age, references, parodies, the internet, an entire prequel trilogy dedicated to Darth Vader's origins, geek culture in general, widely regarded as the end-all be-all of movie twists.

Why It's Okay: I feel like this is one of those spoilers that could only possible be effective if we had time travel handy, went back to 1980, stood in line, and blurted it out. If you're a fan of movies at all, or even just sci-fi, or even just... have a pulse, you probably know that Darth Vader is Luke's father. It's actually gotten to the point where the phrase "Luke, I am your father" gets corrected by fans to "No, I am your father".

If nothing else, one can't possibly be blind to the fact that there's an entire trilogy spanning 1999-2005 depicting Anakin Skywalker's fall to the dark side, becoming Vader. This wasn't any mystery when 'Episode I' was released, it was just out there by the filmmakers. On top of everything else, this reveal is widely known as one of the best moments in cinematic history, and is almost always used as the example clip a scene from the film is featured. Add to that countless parodies, and the only conclusion one can draw is that if you don't know this, you have been leading one hell of a sheltered life.
