William Langston Thornton is best known as the son of acclaimed American actor and filmmaker Billy Bob Thornton and his former wife Pietra Dawn Cherniak. Unlike his famous father, William has spent most of his adult life outside the entertainment spotlight. His limited public appearances and private lifestyle have naturally created curiosity among people searching for information about the Thornton family.
Born on June 27, 1993, William is Billy Bob Thornton’s first son and his first child with Pietra Dawn Cherniak. He has a younger brother named Harry James Thornton as well as two paternal half-sisters. While some celebrity children build careers around their family names, William has maintained a comparatively low public profile. PEOPLE identifies William as one of Billy Bob Thornton’s four children and confirms that he was born in 1993.
Here is a closer look at William Langston Thornton’s biography, age, parents, siblings, family background and interesting facts.

Who Is William Langston Thornton?
William Langston Thornton is the elder son of Billy Bob Thornton and Pietra Dawn Cherniak. His father is an actor, screenwriter, director and musician whose career has included acclaimed films as well as major Hollywood productions.
William grew up with a famous surname, but he did not develop the same highly visible public career as his father. He has occasionally attended entertainment events alongside Billy Bob Thornton, yet those appearances have been relatively rare.
PEOPLE’s family coverage notes that William has attended red-carpet events with his father over the years. Documented appearances include the Rugrats premiere in 1998 and, much later, the premieres of Whiskey Tango Foxtrot and Bad Santa 2 in 2016.
These appearances show that William has not been completely absent from Hollywood events. However, they also highlight how limited his public profile has remained compared with members of his family who work directly in entertainment.
William Langston Thornton’s Age and Birthday
William Langston Thornton was born on June 27, 1993. As of August 2026, he is 33 years old.
His birth was significant in Billy Bob Thornton’s family because William became the actor’s first son. Billy already had an older daughter, Amanda, from an earlier marriage.
William’s younger full brother, Harry James Thornton, arrived the following year in June 1994. This means the two brothers are close in age and share the same parents.
Because William rarely discusses his personal life publicly, little reliable information is available about how he celebrates his birthday or what his everyday life currently looks like.
Who Are William Langston Thornton’s Parents?
William’s parents are Billy Bob Thornton and Pietra Dawn Cherniak.
Billy Bob Thornton is the much more recognizable of the two because of his decades-long career in American entertainment. His acting credits include films such as Sling Blade, Armageddon and Bad Santa, while he has also worked as a writer, filmmaker and musician.
Billy Bob’s full name is William Robert Thornton, which helps explain the shared first name between father and son. PEOPLE reports that William Langston Thornton was named after his father.
William’s mother, Pietra Dawn Cherniak, was Billy Bob Thornton’s fourth wife. The former couple had two children together: William and Harry.
Their marriage eventually ended, but William remained part of a large blended family as his father’s personal life changed over the years.
William Langston Thornton’s Father Billy Bob Thornton
Understanding William’s public recognition requires understanding the career of his father.
Billy Bob Thornton was born on August 4, 1955, in Hot Springs, Arkansas. He became one of Hollywood’s recognizable character actors while also developing a reputation as a screenwriter, director and musician. IMDb lists his birth name as William Robert Thornton and confirms that he has four children.
One of the defining projects of Billy Bob’s career was Sling Blade. His career later expanded through both dramatic and comedic performances.
Despite decades in the entertainment industry, Billy Bob has spoken about keeping some distance from Hollywood culture. In a 2025 interview with PEOPLE, he said that his interests outside work largely center on family, music and film projects.
For William, having such a recognizable father naturally brought occasional public interest even without pursuing celebrity status himself.
William Langston Thornton’s Mother Pietra Dawn Cherniak
Pietra Dawn Cherniak is William’s mother and the mother of his younger brother Harry.
Billy Bob Thornton and Cherniak married in 1993, the same year William was born. Their second son arrived in 1994. Their relationship later ended in divorce.
Pietra has remained far less visible in mainstream entertainment coverage than Billy Bob. As a result, reliable information about her current professional and private life is more limited.
For William’s biography, however, her role is important because William and Harry are the two children Billy Bob and Pietra share.
William Langston Thornton’s Siblings
William comes from a blended family and has three siblings through his father.
His full brother is Harry James Thornton, born in 1994. Harry has developed a more visible public career than William. He has worked behind the scenes in entertainment and appeared on the reality series Relatively Famous: Ranch Rules. PEOPLE has also reported on his work in luxury real estate.
William’s older paternal half-sister is Amanda Brumfield, Billy Bob Thornton’s daughter from his marriage to Melissa Lee Gatlin.
His younger paternal half-sister is Bella Thornton, Billy Bob’s daughter with Connie Angland. Billy Bob and Angland later married in 2014 after being together for many years.
This makes William part of a family whose members have taken noticeably different paths in adulthood.
Is William Langston Thornton an Actor?
There is no strong public record establishing William Langston Thornton as a professional actor.
This is an important distinction because internet searches sometimes describe celebrity relatives as actors or entertainers simply because they belong to Hollywood families.
William has attended movie premieres with his father, but attending an entertainment event does not mean he has pursued acting professionally.
IMDb does list a William Thornton in the additional crew of the 2016 film Bad Santa 2, credited as an assistant to Mr. Thornton. However, publicly accessible credits alone provide limited biographical detail, so broader claims about William Langston Thornton’s career should be treated cautiously.
His current occupation has not been extensively documented by major media outlets.
William Langston Thornton’s Public Appearances
Although William is a relatively private person in terms of media coverage, several appearances with his famous father have been documented.
One of his earliest known public appearances was at the 1998 premiere of Rugrats. William was still a child at the time.
Years later, he attended the 2016 premiere of Whiskey Tango Foxtrot with his father. He also appeared at the premiere of Bad Santa 2 that year.
These appearances provide some of the clearest public records of William as an adult.
However, he has not followed the typical celebrity-family route of appearing frequently in interviews, reality programs or entertainment news.
Why Is William Langston Thornton So Private?
The most accurate answer is that William simply has very little documented public exposure.
It would be speculative to claim that he deliberately dislikes fame or has made a formal decision to avoid Hollywood because there are few widely available interviews in which William personally explains his views.
What can be observed is much simpler: compared with Billy Bob Thornton and even some of his siblings, William has maintained a limited public profile.
There are no widely reported ongoing entertainment projects associated with him and few recent mainstream media stories focusing specifically on his personal life.
His privacy is one reason search interest surrounding his name continues. People know his father’s career well but know considerably less about William himself.
William Langston Thornton’s Relationship Status
Reliable information about William Langston Thornton’s romantic relationships is limited.
There is no well-established mainstream reporting confirming his current wife, girlfriend or marital status. Various biography websites may make claims about his private relationships, but such information should not automatically be treated as fact without reliable sourcing.
For that reason, it is more accurate to describe William’s relationship status as not publicly confirmed.
The same caution applies to claims about children, homes and other highly personal matters.
William Langston Thornton’s Net Worth
William Langston Thornton’s personal net worth has not been reliably disclosed.
Some websites publish estimated figures for celebrity relatives even when there is little evidence about their income, assets or occupation. Such estimates can be misleading.
Billy Bob Thornton has enjoyed a lengthy and successful entertainment career, but his financial position should not be treated as proof of William’s personal wealth.
Without verified financial information or a clearly documented professional career, assigning William an exact net-worth figure would involve speculation.
