 In some versions of the film, dialog has been redone in at last two scenes,  presumably to make points more clear. For example, in Little Petes first  scene, he is asked what his Dad would say about him hanging backstage with a  rock band. In one version, Pete says "Nothing. Hes dead." In the other  version, he instead says "I never met my Dad. Hes some kind of mystery"  (which serves as a better setup for information learned later) Also, Tony  returns to the bands apartment after his release from the hospital, only to  find they have moved out. In both versions, under People Are Strange, we  hear him on the phone with a friend, but the phone conversations begin  completely differently. In one we never learn what happened to the band, only  that they seemed to have moved out and left Tony behind, while in the other  we learn that the band has gone on to big things, with a gold album. Both  versions phone calls end the same way, though, with Tony desperately asking  his friend for money or drugs.
