“Castle Falls” (** out of four) was a serviceable action potboiler about various underworld figures (Scott Hunter, Kim Delonghi, Dave Halls, and others) and a prison guard (Dolph Lundgren who also directed) who descend on a luxury condominium to find millions of dollars but have to first deal with the hard-nosed janitor (Scott Adkins) who found the loot first as every man is out for himself. Moves reasonably quick on its feet and features enough action for fans but gradually devolves into too much murk. Lundgren proves to be a capable action director and actually gets one of his better performances out of himself in this one.
