Visible crew/equipment: After escaping the T. Rex, when Alan and the kids climb the huge tree we can see a bit of what looks like netting at the top right side of the screen and also the set's scaffolding at the left side, then after the scene with Hammond and Ellie in the dining hall, when it cuts back to Alan and the kids we can see much more of the netting behind the tree set, at the top of the screen.
Visible crew/equipment: In the finale, Jessica runs over to Jason from behind and she stabs him in the heart with the dagger. Then, Jason lashes back and hits Jessica, and she goes flying backwards.
