Who Is the Kleinsasser Family on ‘Big Sky’? Here’s What You Should Know

John Wayne Kleinsasser (played by Kyle Schmid) is Horst Kleinsasser’s middle son who believes that he should be the heir to his father’s ranch — not Blake. 

Kyle Schmid explained in a previous interview, “He believes he is very deserving of the ranch, and as Blake has taken off, he feels that it is owed to him, that he should get everything. But Blake returns, it’s dangerous because it threatens what he believes should be his, and you see this whirlwind of a demise.”
