80-90s sci-fi movie in which scientists did something to make the world pitch-black because the ozone layer had depleted

I watched this movie during my childhood. It was a sci-fi movie and the environment is like a cyberpunk game or the Blade Runner movies. The sky was pitch-black all the time because the ozone layer had depleted and scientists did something to make the world pitch-black, like it was night all the time.

The movie is not Habitat and definitely from between the 80s and 90s. The main characters don't believe the scientists or politicians, so they try to reach somewhere to see the world in daytime.

IIRC, at the end of the movie, they finally get somewhere - like changing layers - and see the Sun. Also not sure, but around the ending, there is something like a rocket landing or a launch moment, like NASA's.

Dark City looks so similar and I got really surprised because Jennifer Connelly is in the movie, but I think this is not the one I am looking for. In my movie, they somehow managed to get somewhere to see the Sun, at least, but they were in some room with glasses and watching the rocket launching, I believe.

Is this Highlander II: The Quickening (1991)...?

In the future, Highlander Connor MacLeod must prevent the destruction of Earth under an anti-ozone shield.

Most of the film is set in the year 2024, 25 years after the activation of an electromagnetic shield designed to compensate for the depleted ozone layer by blocking out all sunlight. Some suspect the ozone layer has repaired itself and that the shield is no longer necessary, but the Shield Corporation responsible for maintaining the shield (and greatly profiting from it as a result) insist that it is. The depiction of New York City in this time period is reminiscent of Blade Runner's depiction of Los Angeles.

The film includes a flashback to the shield's activation in the year 1999, which resembles a rocket launch, with a team of scientists holed up in a bunker and using dark goggles to look outside through a window as a countdown ticks down, after which a beam is projected up into the sky to generate the shield. In the theatrical cut, this scene is shown at the beginning. In the longer Renegade Version and Special Edition, the scene is shown about halfway through.



Toward the end of the longer versions of the film, there's also a scene where the male and female leads -- Connor MacLeod and Louise Marcus -- make their way to the top of a mountain, above the shield, and are able to see a beautiful daytime sky without being harmed, proving that the ozone later has indeed repaired itself. This scene is not present in the theatrical cut, so if this is the right film, I'm guessing you saw the Renegade Version, released in 1995.
