Born into affluence is a big deal. Even better is when your parents and siblings are currently the creme de la crème of society, you are never going to suffer. This is the case of Liam Costner, the son of veteran American actor Kevin Costner. If you are familiar with Hollywood, you definitely would have come across Kevin Costner. He is one of the mainstays in Hollywood today.

But that’s not all about Liam Costner. He is also the stepson of billionaire William Koch. In this article, we will explore everything about the young man and show his relationship with his father. Who are his siblings? What is he doing now? All these and more are what we will be revealing. 

Who is Liam Costner?

Liam Costner was born on November 15, 1996, in the United States of America to Bridget Rooney and Kevin Costner. Details about his education are not available on the internet for obvious reasons. If you are wondering why, well, most celebrities don’t put out their private lives on the social media space. His background shows that he was brought up in a well-to-do family and that’s all that matters. 

However, at a young age, his parents separated. Again, another regular occurrence with celebrities. 

Who is Liam Costner’s Father?

It is true that Liam is only starting to make a name for himself but that is not true for his father, Kevin Costner. With two Golden Globe Awards, Primetime Emmy Award, two Academy Awards, and two Screen Actors Guild Awards, you can’t downplay the talent of Costner Sr. Kevin Costner was born on January 18, 1955, in Lynnwood, California, the United States of America to a welfare worker, Sharon Rae and an electrician, William Costner. 

Costner is of English, German, English, Scottish, Irish and Welsh origins. Perhaps all of these had a role to play in the aggregation of talents that he has. In hindsight, is there any role Kevin Costner cannot play? We doubt it. Growing up, studying Mathematics, Physics, Chemistry was not what Kevin loved to do. But poetry, piano, music, sports, you would see Kevin Costner leading in these activities. It was there and then, his parents knew that this particular sin was destined for the arts. 

Kevin Costner graduated from Mt. Whitney High School. He was a member of the musical band. After his graduation, he enrolled in California State University, where he earned a Bachelor’s Degree in Marketing and Finance in 1978. This degree would later become highly useful to him as he ventured into his career.

After earning his degree in marketing, Costner decided to focus on his gift; acting. It didn’t come easy but the same year he graduated, he made his film debut. The name of the film is Sizzle Beach. However, even though it was his debut film and you know how uneasy people get to see their first work out there in public, he had to wait till 1981. The film was welcomed with mixed feelings. Kevin Costner would go on to feature in other films like Bull Durham (1988), Dance with Wolves (1990) amongst many others. 

It was his performance in Dance with Wolves that won him two Academy Awards. From there, there was no going back.
