After Kris and Kelly escape their burning tent and everyone is attempting to put out the fire, there is no longer anything inside the tent - all of the furniture and other items have disappeared.
Helmut forces Kris to change into her costume and her hair is simply parted. Moments later when they practice her has is pulled back and curled more, but she would not have had equipment in Helmut's tent to change her hair.
The knife thrower pours himself a shot of Jagermeister (a dark European liqueur), however the shot he pours is a clear liquid.
When tent is burning down, panicky horses can be heard, but no horses are in the vicinity of the burning tent.
When Kelly makes her motorcycle jump, the end of the ramp collapses before she reaches it, which in reality would have no affect on the motorcycle stunt - other than landing closer than intended. Instead, her (obviously male) stunt double pretends to crash by laying down the bike. Additionally, the stunt double wears flat-bottomed boots versus the heels on Kelly's. And when she gets up after the crash, her jump suit has no grass stains or rips.
