I saw a movie on TV in the 90 and this movie was a fantasy one from 80s and the stronger memory from me is a scene and in this scene there is a woman that enter in some kind of fire, blue fire, I guess, waiting for immortality, but she became a very old lady and dies.
“She” (1965)?
Here is the full movie from YouTube. That scene starts at 1:43.
