Here is 3 off the top of my head: 1- the 4th of July scene. While patroling the waters, hooper is speaking to Brody on a walkie talkie. In the background, you can see guys in a boat dumping stuff out of buckets into the water. It surely couldnt be chum. What is it? 2- also in the 4th scene, Brody yells at the lifeguard, no whistles. Why is he yelling this? 3- when hooper is supposed to get the 1st barrell ready, he instead runs into the cabin of the Orca and grabs something. What is he grabbing and why did he choose to do it at that moment instead of tying up the barrel?
