The first and the last one are the best....ie Chitty Chitty Bang or Johnny Dangerously.
Not sure as to the relevanc of the bowler hat other than having a prop to get arcs with. I dont think yo want to go the rout of having big arcs. How you are going to get your contrast is this guy is very refined and a little more rigid in his movements and much more small. Then he yells and flips out and loses all the composure he had before. Rather than have him do all this stuff I think you should make him as composed and with it as possible to show the big contrast of when he flips out and says to open the door. I feel like the waterfront one is a build of the same emotional beat. For the Johnny dangerously one I do see what you are saying about repeating the same lime I think that as far as your vide reference what you were doing there was working pretty well. I would not set your camera dead on, adn this goes for the other choice too. Have them tree quarters which will make them a little bit more dynamic. Need to see a little bit bigger change in his facial expression and body posture. Maybe he is looking up off in his head he realises that he has got amnaesia.
for the sketches you need to make the changes to the acting beats and then again make sure the camera is more dynamic than having the character flat on.

Of all six clips only number three would really work. So I need to look for some more clips where there are definite changes of direction and different beats
