“#Unknown” (* out of four) was a nearly unwatchable psychodrama about a successful author (Hal Oszan) who starts receiving bizarre phone calls as he attempts to write the follow-up to his lucrative debut but soon finds that the phone calls and stress begin twisting his reality inside-out and causing him to lose his mind. By the end of this mess, you’ll know exactly as he feels. Deeply unpleasant film is a real waste of time. Tom Sizemore is well-cast as a recovering drug addict; whether he is ever able to get his career back on track is the real “unknown.”
