Anthony Hopkins has penned the screenplay, composed the music and plans to direct "Slipstream", a feature based on his own wild thoughts about God, life and death reports Production Weekly.

The story follows aging screenwriter Felix Bonhoeffer (Slater) who has lived his life in two states of existence: the world of reality and the world inside his head. Hired to rewrite a murder mystery set in a desert diner, and unaware that his brain is on the verge of implosion, Felix is politely baffled when.

Christian Slater and Gena Rowlands also star in the project in which actors will play dual and triple roles. Shooting begins in June in Los Angeles.
