In the back yard after the son finds his mother's watch, he gets on his bike to get away from the dish. If you look closely between the part when his back wheel goes off the ground and when he holds onto the post, you will see a pair of hands lifting him off the bike.
Yeah I saw that too! I couldn't believe they didn't spot that in the editing, because it is so obvious... they had obviously never heard of strings or anything either, hey???
Yes, I have also noticed this. I've watched this movie when I was a kid, and then recently bought it. And just noticed it a couple days ago. So funny. Bad bad editing job.
