McQueen a legend and a wind up merchant....
I've read a lot about Steve McQueen upstaging brynner on set, using not so subtle acting technics and kicking over brynners dirt mound (brynner wanted to appear taller than McQueen on screen, so he stood on a giant mound of dirt)...
I also noticed that brynner always appeared downstage at the front of camera whenever McQueen joined him in a scene, to me it seems that McQueen was well aware of his counterparts ego and sort to wind him up constantly, brynner being a little over sensitive....
