Revealing mistake: Check the scene in slow motion when Peejoe's eye gets damaged by a stone flying off from a lawn mower. The eye doesn't get hurt in the shot when it is hit by the stone, and a close-up shot of the flying stone is reversed, i.e. it's actually flying into and not out of the lawn mower, in an angle where it couldn't be just popping up and down.
Revealing mistake: When Peejoe gets hit in the eye by the rock flying from the lawnmower the rock is coming from an angle that is not possible. Based on the angle of the handlebars of the mower it is to Peejoe's left on the right side of the screen. The rock flies at his right eye from off the left side of the screen.
