Director Vince Gilligan creates some profound, interesting scenes with violence. 

The "Saul" clip also recalls a famous cinematic moment in the Frankenheimer film Ronin - one hired "crewman" humiliates another who then retaliates physically - but is defeated utterly by nothing more than a cup of coffee (a weapon-of-opportunity). 

A firearm gives more control (ideally) but there can be no genuine mastery of any situation without fitness/excellence-of-mind. 

The cool, calm brutality of the "crewman" Mike is very similar to that of Kurosawa's rogue samurai (actor Toshiro Mifune) in the classic Japanese movie, Yojimbo (pronounced Yoh-him-boh). 

Mike's character is a little less brutal than the samurai, since Mike doesn't kill anyone in this "lesson".
