"Watch Your Back" (a.k.a., "Killer Photo") is a crackling good yarn. A high-tech assassin is on the loose using sophisticated a photo surveillance operation to harass Sarah Goodall Miller, who has recently married an unemployed writer, Kurt Miller. The Millers seem like the perfect family with the chemistry between Sarah and Kurt and his adorable daughter Teri. But, appearances may be deceiving!
The plot thickens when the Millers appear to be targeted for an assassination. Nearly all of the characters are suspicious in some way, including Sarah's obnoxious, flirty co-worker Jackson, her overly officious assistant Julie, and the neighbor Louise, who is infatuated with Kurt. Behind the scenes, the mastermind of the assassinations is killed in a police shootout, leaving Sarah on her own to set things right.
There is excellent suspense built, and the filmmakers keep the audience guessing as to who is the villain of the piece. The final ten minutes offer the granddaddy of all plot twists, as the rug is pulled out from under the audience. The actress playing Sarah was terrific and very credible with the delicate character transformation she had to achieve at the end.
The surprises come in a fast and furious manner in the thrilling ending! The best advice possible for film viewers is to watch your back!
