The worst David Lynch movie David Lynch never made, Slipstream is a writing-starring-directing-composing effort from Anthony Hopkins. Apparently the stress of the job gave the man epilepsy. A maddening collection of random insert shots, buzzing sound effects, enigmatic characters and a circular, down-the-rabbit-hole narrative, Slipstream makes you long for a pretentious, arty student short. Because those are only about eight minutes long. Hopkins plays a screenwriter called in to save a troubled production, which allows for a lot of movie-within-a-movie trickery. While we try to get our bearings, Hopkins looks as befuddled as we feel, Christian Slater stops by for a Nixon impression and an aged Kevin McCarthy (1956’s Invasion of the Body Snatchers) plays himself.
