Walt Thrombey

Walter "Walt" Thrombey, played by Michael Shannon, is Harlan Thrombey's youngest son and the CEO of Harlan's publishing company.

Personality
Walt, being the youngest, is the least mature and most spoiled out of all the family members. He also seems to be the family's failson. He is the most whiney which may have rubbed off on his "alt right troll nazi" son, Jacob Thrombey (although his wife Donna Thrombey likely had something to do with it too).

While Walt appears to be politically conservative, he does not share his son's far-right views: if anything, he is unaware of what Jacob is involved with.

Trivia

 * There are two deleted scenes regarding Walt: it is revealed that his leg injury (which he attempts to pass off as from a biking accident), as well as the cane he uses during the film are the result of him failing to pay back a loan shark, suggesting that his later avarice towards Marta is out of desperation.
