Visible crew/equipment: In the last scene when Peter is in the tree house, blue tennis shoes are moving up and down. This is most likely a camera man (or woman) trying to get angles.
Suggested correction: I watched this entire scene three times and couldn't see any blue tennis shoes moving up and down. Most of the shots in the scene are close-ups of Peter's face. If the mistake is valid, then a timecode and/or a picture would be really helpful, as the scene lasts for a couple minutes.
