I don't know about 9D, but I once saw Avengers: Age of Ultron in 4D in a theater in Seoul, South Korea. It was a 3D film with moving seats, smells, and air that would blast in your face.
During a car chase, you could smell burning rubber, or close-ups of women would have a whiff of perfume or flowers. During a shootout, you'd get fine blasts of air on either side of your face, like bullets barely missing your head. If someone took a hit, the seats would jolt violently. It also poked you in the back if someone was hit from behind. Not to mention, flying in any aircraft felt like you were on a rollercoaster; the seats would raise and lower and tilt in all directions. It was pretty intense. Like being on one of those Universal Studios rides at their theme park, except for an entire film.
Dude I wish those kinds of theatres were more common. Disney has (or had when I was there last anyway) Honey I Shrunk The Audience and A Bug's Life as 4D experiences, and those were awesome.
This is a PSA but there are a handful of theaters that do 4D called 4DX theaters and you might have one near you if you live in the US. Regal theaters specifically usually have them.
Went and saw Dune Pt2 in theaters and it was actually super fun. Shaking during the fight scenes, wind on your face when out on the dunes, lots of movement riding the sand worm, and water blasts and more.
They’re super fun, look them up and maybe travel to one sometime.
When I was a kid in the mid-90s, I went to Universal Studios in Orlando and experienced T2-3D: Battle Across Time, their Terminator spinoff story. It was amazing! 3D visuals, spraying mist into the audience as machines are blown apart, and there was audience interaction too, where the story would "leap off the screen" and actors would duke it out in front of us. I always wanted to go back and experience that again, but I guess they finally closed down that ride about a decade ago.
Unfortunately, Honey I shrunk the kids is no more and I heard that they are getting rid of A Bugs Life (although that might just be a retheme)retirement.
The Star Tours ride moves around while you're in it and the Avatar ride moves and puffs smells while you fly on the back of the flying dragon animals, but I think that's the closest experience to 4D now.
Disney's California Adventure has one that was recommended to us where you fly over parts of California, but it was unimpressive. Also, it apparently was highly dependent upon where they seated you because we were getting perfumes blown right in our faces rather than getting vague wafts of smells like were obviously intended.
Like at some point, after your standard 5 (vision, sound, touch, taste, & smell), those dimensions gotta start wrapping back around to where they started. And at that point they must have to go THROUGH your tissues to do it.
I am saying that one of them surely is an electrified butt-plug. So that's six, and after that... that's where shit REALLY starts to get freaky!
Let's not even go into whoever they dropped in after he left the tattered franchise. Oddly enough, the Hulu reboot/continuation(?) wasn't that bad. Further note, it's weirdly connected to an upcoming tenforward post I'm slapping together.
Believe it or not, in certain contexts, this is an appropriate use of dimension. Dimensions can be thought of as parameters, essentially. In 3d space, you have 3 parameters, length, width, and height. Add in time and you have 4d spacetime. From there, if you're defining a system with more parameters, it's a higher dimensional space. A movie with 3 spatial dimensions, then programmed smell releases, like someone else mentioned, would then be 4 dimensions: l,w,h,s. The reality is, it's a bit silly and definitely a marketing gimmick to refer to your movie experience as "9d", but it's not entirely incorrect.
3 of space, and 6 of time. You're only missing 2 dimensions of time from 11D. Personally, I think the decision to not include the last 2 time dimensions is a bit too avant garde for my tastes.
Dimensions don’t have to be spatial or temporal. They can just be parameter spaces. So, how much water sprayed on you during the ride is a parameter with a value and hence a dimension.
But yeah, this marketing phrase is only going to impress someone with the education of a six year old child.
I've seen Kung Fu Hustle and Shaolin Soccer here in the U.S. They were a lot of fun. And holy shit, I just read that he made the highest-grossing and second-highest grossing films in China.
Also, this bit from his Wikipedia page is amusing:
In 2013, Stephen Chow was elected a member of the 11th Guangdong Provincial Committee of the Chinese People's Political Consultative Conference (CPPCC).[39] According to media exposure, Chow often arrives late and leaves early at the conference, and has not put forward any proposals.[40]
I think m-theory pushes out to 13. String up to like 11. It gets mind melting after 5 because things are more existential based, not just simple physical properties. Like timelines enveloping time and dimensions within but expressing the conditions of existence. So it's like you can totally travel to the future, but not in your own timeline. You'd need to locate where the future is "waiting" and manipulate things in such a way that it triggers without existing in your timeline. Since in order to return to the present, you'd need the future to still be waiting and every atom in your existence continuing as it did to continue to that future, which isn't there yet, but exists... So that's simple. But now where and how are timelines sustained? They can't operate at the same time because time can be "distorted" in one place but not another resulting in different time values. There must be a dimension that expresses and governs this so universes remain connected but have their different dimensions and rules within.
And it just keeps getting more and more mind fucky. If you were experiencing 9D—you actually are but don't realise it—youd lack the mental fortitude to appreciate it, since your mind would be needing to be constantly understanding and perceiving 5 additional dimensions beyond time.
