Go to the end of the movie at the garage of Clear´s house just 3 minutes before the power line throws Alex back! You see Alex running through the forest and everywhere is mud. The ground is muddy and the bushes are pretty wet and then you see how this huge tree gets hit by a flash and tips over on Alex. Alex is sticking clearly right in the mud and in all the dirt under the tree. Logically he has to be very dirty and wet now, I mean especially his clothes need do be very dirty and wet! But then after he got himself free you see him running over to Clear that is sticking in her car. As Alex starts to talk to Clear watch him carefully. He really is dry again and his clothes don´t even show the tiniest piece of a hint that he was sticking in mud barely one minute before!
