Although a lot of earlier aircraft had longer control sticks to give more leverage, my bet is that that was a movie-ism so you could see what he was doing. Otherwise a guy flying around in a movie just looks like he's jiggling in his seat and shouting to nobody for no reason. That's why in top gun they kept cutting to quick shots of the throttles being slammed forward and the stick being yanked back, to make it look like they were actually doing something.
