When Eye Guy's detached main eye blasts the Blue Power Ranger, if you look closely you can see that the Blue Ranger is taking the attack to shield a seated Japanese child behind him. This child is not seen later when the Blue Ranger leaps to take out Eye Guy's main eye with his Power Lance, which means this was footage of the Japanese Zyuranger series.
When the rangers and Willie are in the park and are attacked by Putties, Jason orders the rangers to fight. In the shot showing a terrified Willie in the center of the circle, you can see that Billy isn't fighting the Putty that's in front of him. He and the Putty are just facing each other and are barely moving.
When Eye Guy shoots fiery eyeballs from his body at the surrounding Power Rangers, most of the Rangers fall back well before they are hit.
