Address Unknown is a very enjoyable film, especially because of its intelligent direction of actors, and the talent and personality of its two chief teenagers: Kyle Howard and Johnna Stewart, even if Howard looks younger than his character and himself are. I expect to see more of them. The trouble with this film is that once you have seen it and enjoyed it, the falseness of its initial sequence is evident. What were those two characters doing with a bag of U.S. Mail? Why was it in their hands? Why was it so important to them since it did not contain anything of real value, except a letter from one of them that was important only to the recipient?
