Other mistake: While laying the pipeline toward the ocean, the pipe is being joined so that the female end flows into the male end. The male end should flow into the female end.
Continuity mistake: In the ending scene with Daniel and Eli, Daniel starts yelling at Eli as Eli is running down the bowling alley. As Daniel is throwing bowling balls at Eli, the first ball is thrown down the left lane, hits Eli in the foot and ends up in the right lane - no pins have fallen. The second ball is thrown down the left lane and is a gutter ball - again no pins have fallen. The third ball is thrown into the right lane, hits a bucket and presumably hits no pins. However, as Daniel is chasing Eli behind the bowling alley you can see that the left lane now shows only 2 pins still standing.
