Just because the Little People, Big World patriarch, Matt Roloff, is a reality star, doesn't mean he's not chummy with some very well-known actors in the movie industry. Actually, it's quite the opposite. Matt is best friends with Marty Klebba, a real actor who has appeared more than 30 times on LPBW since 2006. However, those cameo appearances on reality television are far from Marty's expertise. Keep scrolling to learn more about Matt's friend Marty!

Marty Klebba is best known for his role in Pirates of the Caribbean.

The 48-year-old plays the role of Marty — one of Captain Jack Sparrow's black pearl crew members. Not only does he play the iconic character, but he also has a good relationship with some famous faces like Orlando Bloom and Johnny Depp.

He was born with a form of dwarfism called, Acromicric Dysplasia.

He stands at 4 feet, 1 inch tall. Matt has a different kind of dwarfism, known as Diastrophic Dysplasia.

Despite his successful career, Marty also has a solid family life.

He married his wife, Michelle Dilgard, in 2011. Together, the couple have two children, Alec, and Makenzie, 5.

He is a huge advocate for giving back to the dwarfism community.

Marty runs a nonprofit organization with Matt called, Coalition for Dwarf Advocacy. According to the website, the charity was formed to help people with short stature in medicine, vocation, education, adoption, and public accomodation. All of the donations received by the foundation go directly towards individuals with various forms of dwarfism.
