Could it be "Boa" ?

Sounds like it could only be one movie.

Looks like a good time for a sing-a-long kids......ready.....






In the town where I was born,
Lived a man who sailed to sea,
And he told us of his life,
In the land of submarines,

So we sailed off to the sun,
Till we found a sea of green,
And we lived beneath the waves,
In our yellow submarine,

We all live in a yellow submarine,
Yellow submarine, yellow submarine,
We all live in a yellow submarine,
Yellow submarine, yellow submarine,

hehehe, the movie is not really about a submarine, They just use it in the begining to reach the research center or whatever, since it was located under the ice, the only way to reach it was with a submarine. well it made sence to me then anyway.
And it is not a "hidden world" they find, it is a man buildt construction.
Not "boa" this one is from the eightes, or earlier.

Deep Shock.

It sounds like it MIGHT be "Endless Descent" aka "The Rift"

Yes, this must be it, illegal genetic experiments, mutant creatures, and submarines.
I have a strong feeling that here in sweden, the movie was called the same as "the abyss", making it impossible to find.
But 1990 !? it feels late, but this must be it.

Aaah yes, "The rift". Of course.

This thread actually makes me wanna see it again. Remember it beeing pretty good, or at least entertaining. Of course, it´s been 15 years, soo...:rolleyes:

Yes! thanks alot! this is definitely the one. I found the Swedish name for it.
The movie "the Abyss" is called "avgrunden" wich means just 'abyss' or 'chasm'.
and "the rift" is called "sprickan till avgrunden" meaning sort of "the crack to the abyss"
Now when i know the name of it, it will probably be easier to find.
I surely will be dissapointed when I see it as any other movie not seen in about 20 years, but now I just must see it.
Thanks again!

Uh....I thought I might as well mention, the last time I saw this was the first time, and that was in 1990 with some friends. And.....there was a lot of stupid stuff in it mixed in with the fun stuff. Careful there!
