Continuity mistake: After Toady realizes what the burning fuse is for, and the explosion occurs, his hat is blown off, and he starts to shield his face with his arms.

Continuity mistake: As Max gets out his car after first finding the Gyro Copter there is a shot from directly above him and you can see no shadows behind his car on the sand, then as the shot changes to Max's' face as he approaches the Gyro Copter there is a long deep shadow of a tree branch cast just behind his car.
