Owen was born on November 18, 1968, in Dallas, Texas, and he gained fame during the 1990s and 2000s with his roles in popular comedies like Wedding Crashers, Zoolander, and The Royal Tenenbaums.
In fact, he co-wrote The Royal Tenenbaums with director Wes Anderson, which earned them an Academy Award nomination for Best Original Screenplay.
Wilson's career also features voice acting, most famously as Lightning McQueen in Pixar's Cars series.
Recognized for his unique charm and his famous 'wow' catchphrase, he has become a cherished personality in Hollywood.
The Loki star is one of three siblings. While both of his brothers are involved in the industry, his younger brother is particularly famous.
A viral TikTok video featured someone reacting to images of the Cars actor's celebrity sibling, and since then, the clip has gained millions of views.
In the video, she commented: "I was today years old when I realized this guy is Owen Wilson's brother. Tell me I'm not the only one that just clocked?"
Fans were taken aback and quickly flooded the comments section, with one user saying: "Now I know why he looks so familiar. Never thought about them being brothers!"
Another commenter wondered: "How did I not realize?"
A third person chimed in, "Why does this make so much sense? I always thought they looked similar,"
However, some people were not as surprised, seeming to have been aware of the famous siblings for quite a while.
One commenter remarked: "Girl what?! Everybody knows they are brothers, they talk exactly the same!"
Another person added: "Am I really old? I thought everyone knew this."
A third individual said: "How did y'all not know this? Me and my friends used to call him 'the hot one.'"

Luke has also received critical acclaim for his performances in some lesser-known films, such as Henry Poole Is Here, Death at a Funeral, and The Goldfinch.

Andrew has shared the screen with his famous brothers several times, including in multiple Wes Anderson films, such as Bottle Rocket, Rushmore, and The Royal Tenenbaums.
The three siblings were raised in Dallas, Texas, and are often spotted cheering each other on from the front row at movie premieres.
Their parents are also quite notable, with Robert A. Wilson working as a TV director and Laura Wilson being a respected photographer.
Robert passed away at 75 in 2017, and he and his wife had been married for 54 years.
