When it was revealed that the Mariner rejected Helen, when she offered herself to him, because he knew she didn't really desire him (she had done so only to relent him). The realization that he did not take advantage of Helen at the time because, in contrast with his rough edges, he was a man of true character, was very powerful.

A few minutes to the movie, when Mariner wrecked that one Drifter's boat while being chased. The way he operated his boat is really cool and at that point I know it's gonna be a fun movie.

The moon scene leading into the swimming scene. Absolutely gorgeous and the music is some of the most mesmerizing music ever composed. I was 14 when I got the soundtrack, which I got before seeing the movie. I remember listening to that track in my mom's car on an overcast day while gentle raindrops pelted the windshield. I was hooked on that scene before I ever saw the movie.

Love it when Dennis Hopper says to the girl, offering her a cigarette.
"Nothing like a good smoke if you miss your Mom"
As mentioned, the old guy in the tanker with his Oh, Thank God on getting blown up.
When the girl asks Hopper as the tanker bursts into flame "Was this your big vision?"
Also dug that Hopper was a descendent of The Capt. of the Exxon Valdez and it had become a family stain of "persecution" and he had become St. Joe
Movies is really not that bad. Not great but definitely entertaining and the hype on production delays and re-writes killed it at the box office. It shouldn't have tanked as hard as it did but shouldn't have been a huge hit either.

When Jeanne Tripplehorn drops her dress I knew that this would be a film that I would revisit many, many times over the years.
And I have. I really have.

Costner at the beginning running away from the smokers while working the boat's mechanisms and the soundtrack going nananananananananananananananananana and then he does the "you're dead" sign to the bad guy

I think that moment where you get the wide shot reveal of the Smokers' ship. Up until that point it was always kind of ambiguous as to where they were, then suddenly it all made sense.

Not sure, but it was probably one of the scenes stolen from The Road Warrior.

One of my favourite films, but weirdly enough; the scene for me is when the film begins. He's on his own and you get the sense he's been doing this for a long time and things haven't started going
wrong
just yet and everything seems kind of perfect in what is actually a post-apocalyptic world. I just instantly imagined a world where Humans just simply live on water floats permanently and trade amongst each other. It's basically EVE Online, but in a Waterworld.

My favorite line came right after he dropped that flare into the oil on the tanker, and as it began to explode, the old man in the boat that took oil depth measurements said "Oh thank God!"
I laughed so hard I almost passed out!

All of them.
Let's have an intelligent conversation here: I'll talk, and you listen.

I loved The Movie. Costner,Jean and The little girl were all likeable,but The Smoking part really put me off. I am a smoker myself but thousands being a flop.

the first scene where the universal globe logo is incorporated into the story

Mine, also, is when the Mariner goes "fishing" (using himself as bait)! That scene made it for me, too!
"I'm gonna hunt for U, I WILL find U, and I will KILL U"! L.Neeson - TAKEN

agree with the op wholeheartedly such a beautiful scene so haunting.

Hmmm. I guess it depends on what you watch movies for. It's easy (for filmmakers) to engineer an action scene. The scene in Jurassic Park that made me settle in for the rest of the movie was when Neill turns the other archeologist's head and we pan to the dinosaurs. How many dinosaurs? All of them.
The scene in Waterworld that told me that the film had integrity and quality is the scene with the other crazed sailor, which brings together quality acting, quality directing, and quality plot point in what looks like an action film.

Some scenes of this movie, including the one you mentioned, are very beautiful.
I for one love the under water kiss.
Boycott movies that involve real animal violence! (and their directors too)

"We can start with that wee orchard you have over there."
I enjoyed the hyperbole.
