Body Analysis: Confidence

I chose this clip from Hitchhiker's Guide to the Galaxy, focusing instead on Zaphod. Zaphod is a very confident and "charismatic" character, and he's totally relaxed and open in most of the scene. He makes fun of Arthur when he sees his dominance being challenged, immediately trying to affirm his position as the dominant one.
At first he's very straight, pointing his gun at the pair, then he's got his arm so casually around Ford.
