Eternity (1990)

Television producer James has an extremely vivid dream, in which he is a Prince struggling to keep the kingdom at peace against the wishes of his warfaring brother, while at the same time competing with his brother for a woman's love. The figures in his dream match those in his real-life, with his brother being an aggressive business man trying to buy James out, the King being James' advisor, and the woman being an actress recently cast for a commercial at his studio. Seeing his dreams as a message about his life, James decides to act on their guidance, even though they lead him into the fight of his life.
