Five guys, beaten and bloodied, wake up locked in a warehouse with no idea who they are or how they got there. That’s the premise behind Unknown, a shonkily assembled thriller that tries to combine elements from Reservoir Dogs, Memento and Saw. With such a threadbare set-up, this type of drama lives or dies on the characters, and with a cast this solid that shouldn’t pose a problem.
Tragically though, the actors deliver a clutch of half-baked performances without hint of improvisation — something badly needed to excite the toothless screenplay. Ungainly flashbacks and cut-aways to a redundant subplot dispel much of the tension, resulting in an unsatisfying experience for all concerned.
