Here you go, Sophia.
The best part of
Raise The Titanic. It was so good they showed it twice, the second time was during the end credits (just the part after the ship reaches the surface).
That 'groaning' sound during the close up of the bow after it breaks the surface still creeps me out after all these years.

If you watch it from 4:40 onwards as the camera moves from the stern to the bow you can see a little guy who looks like he's operating a pump or something by winding a handle - it was a gag done by the special effects people to see if anyone would notice.
Funny thing is - I'm sure I saw another version of this where there were 2 little guys operating a pump or whatever which looked a bit like a see saw with one at each end in that same spot? Not too sure? Might have to get my BluRay out and see if it's different.
Also, there are large 'rings' attached to the deck spaced out along the length of the model on both sides, you can see one in the attached image which also shows the guy operating the pump or whatever. These 'rings' were not on the real Titanic, of course. They were put there so crane hooks could be attached to the model for lifting it and they didn't bother taking them off when the model was filmed (hardly anyone would probably notice them anyway).
Another oddity is the wreck been shown with the second funnel missing and the first one still intact. Survivors were pretty much unanimous in their testimony that the first funnel fell before any of the others. I guess the film makers decided it looked better with the second funnel missing and not the first otherwise it may have looked more like a 3 funneled liner?
Of course, we now know all 4 funnels came off long before the 2 broken sections of the Titanic hit the bottom but this film was made 6 or 7 years before the wreck was discovered which is also why the wreck in the movie is in one piece because no one knew with any certainty that the ship broke in two despite many survivors testifying at the hearings that they were sure it had.
