Building the full scale cockpit, I watch ESB all the time looking for details, part identification, etc. Earlier this year I noticed for the first time that, when our heroes are fleeing the empire from the Hoth base, HF leans into the vertical gauge/slider panel as if to adjust something. Funny thing... there is nothing there. He's not adjusting/touching anything. I had seen that same scene 1,000 times and it never occurred to me until I thought about where his hand actually was.
What a great topic!
