Everyone knows funny man Owen Wilson. And most teenage girls (and women) have swooned over Miley's fiance Liam Hemsworth. But did you know that Owen has more than just Luke in his family -- he also has brother Andrew Wilson? And that Liam Hemsworth and brother Chris Hemsworth of 'Thor' fame also have an older brother of much less renown? Check out these famous actors and their brothers in the business who you may not know.

Frank Stallone

Frank Stallone, younger brother of Sylvester Stallone, is an entertainment force in his own right. Though he never achieved the fame of his older brother, Frank Stallone is a Grammy Award Nominated songwriter and has appeared in many movies, including small roles in several of his brother's 'Rocky' movies. (See him rock out in the 'Far From Over' video.) Some may remember him more as a joke target than a talented actor -- in the mid-90s, Frank Stallone was the subject of a running gag on 'SNL's' Weekend Update. Host Norm Macdonald would attribute causes of news stories to "You guessed it - Frank Stallone."

Luke Hemsworth

Luke Hemsworth is the older brother of more famous heartthrobs Chris and Liam Hemsworth. Luke has acted in multiple Australian TV series including 'Neighbors,' on which his brother Liam also appeared. We may see more of Luke in the future -- rumor has it he's signed with the same agency that represents his brothers in the US.

Andrew Wilson

Many people are surprised to learn that Luke Wilson and Owen Wilson, who appeared in 'The Royal Tenenbaums' together, are brothers. They'd be even more shocked to learn that there is an older Wilson brother as well, Andrew Wilson. Andrew is also an actor and director, albeit, acting in much smaller roles. He is by no means ignorant of his celebrity status, however. In response to an interviewer who told Andrew that he didn't know he existed, the actor replied, "Perhaps you missed my turn as a gay cop in 'The Big Bounce?"

Clint Howard

With eight Murray siblings, its easy to lose track of a few. But have you heard of one of Bill Murray's siblings, Joel Murray? Joel Murray is also an actor, appearing in both film and on television. Recently, he's had a recurring role on 'Mad Men' as copywriter Freddy Rumsen. He also runs a restaurant with his brothers named after the movie 'Caddyshack,' which features his brothers Bill and Brian.

Charlie O'Connell

Yes, Jerry O'Connell has a look-alike brother. Charlie is also an actor but he is best known for his appearance on 'The Bachelor.' As the bachelor on the show's seventh season in 2005, Charlie chose Sarah Brice. The two had an on-and-off relationship until 2010 when they officially called it quits.

'SNL' Weekend Update host Seth Meyers' brother Josh is also an actor who plays mostly comedic roles. You may remember Josh in 'That '70s Show' as character Randy Pearson. (He joined towards the end after nearly every other cast member jumped ship.) A cast member on 'MADtv' from 2002-2004, he was on TV at the same time as his brother Seth. This prompted Seth to go on "Weekend Update" to tell his dad to turn off 'MADtv.'

Don Swayze

Blake Lively's real life brother Eric (not to be confused with her 'Gossip Girl' character's brother Eric van der Woodsen) actually broke into the entertainment business before Blake. It was Eric who first asked his agent to send Blake on auditions while she was still in high school. Eric Lively made his debut as a baby in 'Brainstorm' and recently had a guest appearance in Lifetime's 'The Client List.' He also had a starring role in 'The Butterfly Effect 2.'

Doug Pitt

Have you ever heard of Doug Pitt? Neither had we until this recent Virgin Mobile ad. Doug is hilarious in the spot, taking us on a tour of his house in the style of 'MTV Cribs.' He may look nice and ordinary but the other Pitt has done well for himself -- in 2010, he was named Goodwill Ambassador for Tanzania.
