Max: We'll go on the count of three.
Max and Pig Killer together: One...
[Max yanks the door open.]
Pig Killer: What happened to two?
When Mad Max is sent on gulag on a horse, they place a jar of water on a stick tied to the horses head in order for the horse to keep walking "towards" it. When the horse drop dead to the ground you see the jar empty on the ground and no trace of water in or around it. In a few shots later you see the jar again, but this time the ground around it is wet.
