There are two bass guitar players on the stage during the first song sung by Sondra Locke ("One Too Many Women In Your Life"). One is standing on her left and the other is seated in the back wearing a white shirt and bluejeans. There are not two bass tracks in the song.
When Clyde is "scrapping" Patrick Scarf's Cadillac, we see him just tapping the roof of the car, but in the shot from inside the car, the whole front of the roof of the car being caved in. In the next shot we see Clyde just tapping on the roof again, while the roof is back to its original shape.
During the scene near the end where Beekman and his partner run from the Black Widows (and the hit men), Cholla reaches into the limo and takes the keys. While the camera angle is behind Cholla, you see him raise his hand above his head while holding the keys. Yet, as the angle switches to his left, his arm is just coming up from hip-level.
In the exterior (parking lot) scene when Philo's mother arrives at the Pink Cloud Motel and catches the booking clerk peeping in the window of Cloud 8, the door of Cloud 7 is visible and has the hinges at the left-hand side, its lock and handle on the right-hand side, and a sign saying 'Cloud 7' to the right of the doorframe. This is the room that Luther and Loretta Quince are in. A few minutes later, after Orville rams the Quinces' car and the police cars pursuing him frighten off the heavies, Luther peeps out the door of Cloud 7 and reports back to Loretta, "Somebody just bashed into our car, honeybunch." At this point, the door is hinged on the right-hand side and the 'Cloud 7' sign is on the wall to its left.
When the Black Widows are chasing Philo thru town, they end up passing under an asphalt spray used by the paving crew. Hot asphalt ranges from 200° to 330° depending on the mixture. Those temperatures would not only slow down the Black Widows, but would have caused severe, if not fatal burns. Nothing they would have walked away from.
When Philo tells Clyde to, "scrap the Merc" he proceeds to do. However, just before Clyde removes the left fender of the "merc", a hood ornament is clearly seen. The hood ornament is the Lincoln "L", which was not used on the Mercury line.
When Philo is dragged along the ground by Clyde, Philo is lifting his own head up off the ground every time he is pulled along. However, he's supposed to be unconscious from the knock to the head from the butt of the shotgun. He should not be able to pull his own head up every time he was pulled along.
