Continuity mistake: When Jerry-Lee is at the breeder's home, he starts to eat some flowers. In the first shot he picks up one stem of flowers and pulls them out of the vase. Camera cuts and he starts to pull them out again.
Visible crew/equipment: When Dooley breaks down at the start, just as Jerry-Lee jumps out the car there is a bright light reflected on the back of the car's wing mirror. There is nothing around to be a source of the light.
