Which movie was that?
If you watch it, make sure you watch the U.S. theatrical cut, not the slightly longer international cut.
Many complain about the international cut mainly because it uses different music, and not the Tangerine Dream music/soundtrack.
Oh, and Tim Curry does not play the Devil.
The movie clearly shows him talking to the Devil/Satan/Lucifer/whatever name you want to use.
He plays his son and his name is Darkness.
