Character mistake: When David Frost interviews the fictional actor Bryan Martin, he adds a last question to the interview saying "before you go" and acts as if the guest is not gonna stay (as it often happens in talk shows, when some guests, especially the more famous ones, leave after their bit is over). However Martin is staying and in fact there is a special mystery guest a bit later that makes sense only if he is in fact staying. (00:02:00)
Continuity mistake: Matt and John Eagle put the alligator in the cage in Chuck Norris' first scene. Both of them are significantly more covered in mud for their close-up that ends the scene, once they have already closed the cage and are taking a breather, compared to the rest of it. (00:09:25)
Visible crew/equipment: Near the beginning, at the start of the big car chase down the hill, there is a guy blocking another guy's vehicle. The blocking car is red and backs up before turning onto another road. The reflection of the entire camera crew is visible in the side of the red car.
