Variety reported yesterday that our brains may soon be melted by another Philip K. Dick story on the big screen. This time around, it's "Ubik," regarded by many as Dick's master work, getting the film treatment. The cinematic effort will be produced by Celluloid Dreams, and Dick's daughter will be intimately involved. Celluloid Dreams has been responsible for several recent critical successes including "Persepolis," "Son of Rambow," and this year's "Funny Games" reboot.
