Thanks to Jeff for the link!
In the clip below, we see the character Ralphie lie about not not knowing where Flick is when he is asked by the teacher. When the teacher asks Ralphie if he knows where Flick kid is, you can see a single head nod yes before he begins to shake his head no. The slip occurs at about 12-13 seconds in the video at the link below.
Could this be a potential slip? Its difficult to know, since these are actors. However, if this occurred in real life, it could potentially be a hot spot where more questions may need to be asked.
Looks to me along with the head nod before the head shaking that their is a partial shrug with the right arm as well.
There was definitely a hand-shrug while he shook his head no. Good catch!
I’m glad you guys were able to post this. Now that Chris mentioned it, I see the hand shrug as well. I totally missed the hand shrug when I saw the nod. I guess this shows just how observant you have to be and that you can’t focus on just one area.
