I remember very little of the actual setting, definitlly not enough to find it via browsing the net, so maybe asking "personally" gives another chance.

It was a Dr. Jekyll and Mr. Hyde movie. I don't remember who played in it, nor anything specially applying only this movie during the film, what is bad news, BUT I DO have enough information that someone who saw the film be able to help me.

So, this was a colored movie, made before 2000. The story did not distinct from the original writing, making hard to identify. What actually makes able people identifying the film is the ending screen.
The ending after the scientist dying switched to a farm-like house or something where the story was actually told by the fiancé of Dr. Jekyll to a man. Then the camera gets fixed on a child. The child has a disfigured face, obviously meaning he is the child of the dosed Dr.Jekyll/Mr. Hyde. Then comes the list of the crew.

I know it is not much, but let's see if someone can point to it.
