actress: gillian anderson [1]

I was watching “Alone” a few days ago and I noticed Scully make this hand gesture and I thought to myself that seems like something Gillian would do not Scully. So being the nutty fan that I am I had to look into this. So I find out that part in the episode was improv and I go I knew it! I found these other photos of GA doing this hand gesture thingy…Am I the only one to notice this?
