Blue flame of immortality!

Tools    





I'm sorry I don't remember too much but there was a scene in the movie about a man and woman, possible with ancient greek-style surroundings, entering a blue flame which could give them immortality. The film was a bit grainy as it is an old B movie, I believe. I wish I could remember more. Any assistance would be wonderful. Thanks!

ps - I tried to ask for help with the name of this movie in the title of the post but apparently it is not descriptive enough to actually ask for help with finding the name of a movie in the title of a post asking for the name of a movie. ;[

The part with the blue flame is near the end of the film -- watch it here (at around 1:42:00 seconds):
