The first time Bad leaves Jean's house, the left front fender of the Suburban says "Silverado", the second time he leaves Jean's house, after the roll over, it says "Scottsdale" which means they used at least two trucks.
Bad is driving down the road in the '78 Suburban that has old faded paint. When it is rolled down the hill, it has suddenly been freshly painted exactly like it appears in its next scene, which occurred after repairs had supposedly been made. The sequence of filming was apparently to wait until the all other scenes had been made using the Suburban and then rolling it down the hill.
When Blake re-enters the stage at the bowling center, he puts his hat on loosely with the brim tilted to the front. A second later in the following shot, his hat is on tightly, with the brim tilted to the rear.
When Jane forces the truck door open to flirt with Blake, she stands in the doorway with her right hand against her right lower back. Seen from inside the truck, she has it elevated and holding the doorframe, supporting herself on the running board.
During the scene where Tommy meets Bad at the restaurant and Tommy has a bottle of Smart Water filled with whiskey you can see the bottle changing positions between each cut away, or see how it was moved between each take.
When Blake enters the rear entrance of the open air venue in Phoenix, reflections of the camera operator are visible in the red truck. When Blake and Tommy talk in the outside after the bar scene, reflections of the camera team are visible in Blake's sunglasses.
When Bad and Wayne are out fishing, as the camera draws back for a long shot, you can see mountain tops in the upper left hand corner of the screen just above the tops of the trees. There are no such mountains anywhere around Houston.
The goof item below may give away important plot points.
In an act of contrition Bad turns over the large song royalty check he has just received to Jean Craddock admonishing her to use it for her son's future. However, as it would have undoubtedly been made out to his name she would have been unable to cash it.
