Watch the scene just before Tommy is shot and killed. The Warden offers him a cigarette, a Marlboro. Look on the side of the pack. At first I thought this may have been a surgeon generals warning which may or may not have been around in the late 1960's. However, a closer look revealed that there are actually Marlboro Miles on the side of the pack. Being a non-smoker I had to check, but indeed, Marboro Miles is an ad campaign conceived a couple of years ago and did not exist in the 1960's.
