Ok in the scene where Priscilla's parents come to visit out in LA. You will see Elvis and Priscilla sitting on the couch, Elvis will be smoking a cigar, and all of a sudden if you look real carefully while the camera pans away from them meaning a far off glance you will see him chewing something, then when you see his face again in the same scene he has a cigar in his mouth, but no gum or what ever he was chewing.
