In the scene with the corpses lined up on the ground next to the downed aircraft some can be seen changing positions slightly while Will's back is turned (e.g. crossing or uncrossing their legs).
At 16:50 in the movie you see a sign in different languages. In German they say Stop the profession instead off Stop the occupation. Probably a google translation.
