Visible crew/equipment: Near the end of the film after Russell and his buddies have stormed the camp and rescued Meg's husband, Russell sets a claymore mine on the escape path. As soon as the bad guys get close to the mine, Russell detonates it. If you look above the two bad guys as the mine is detonating (just before the camera cuts to Russell and back), you can see the wires they are harnessed to.
Visible crew/equipment: In many of the fight sequences, wires are visible on the actors when performing high jump kicks and/or acrobatics, for example, the first time the main character encounters zombies in hand to hand combat, a rope harness can be seen pulling the zombie back towards the tree.
Visible crew/equipment: When Kitano approaches the girl in the forest to give her an umbrella you can see a microphone positioned between them. It looks like they angled the shot so it would be hidden by the actress' body. (01:24:30)
Visible crew/equipment: When Sebastian is stalking his neighbor and looking at her to see if he can see her undress in the beginning, there is a brief moment where you can see the reflection of a camera crew in the window looking into Sebastian's apartment.
Visible crew/equipment: Right before he discovers the knife that killed his girlfriend, someone's hand is visibly scaring the crow off the top of the filing cabinet. (00:18:00)
Visible crew/equipment: Just as the SS-33 sets off we see the crew on board say "all ahead two thirds". As they say this the camera moves behind a ladder resulting in a camera shadow on the ladder. (00:20:50)
Visible crew/equipment: In the scene where they are getting ready to leave, it's dark and George Clooney is in the wheelhouse - you can clearly see a face of a crew member in the depth finder.
