You might be surprised at how little acting experience the majority of the "Step Up 3D" cast members have. What they lack in acting experience, they make up for in dancing ability. Many of the "Step Up 3D" cast members have been in music videos or gone through formal dance training. Since the movie revolves around dancers, it is nice to see the cast members have the skills to perform in their own dance sequences, which is a huge part of the movie. 

Rick Malambri This “Step Up 3D” cast member started acting in 2007. His first notable job was a small role on “How I Met Your Mother.” The part was so small his character did not have a name and was credited as the "floppy haired guy." In 2009 he had a small role in the Bruce Willis movie “Surrogates.” After starring in “Step Up 3D” as main character Luke, he gained parts in the movies “A Holiday Heist” and “We Are Champions.”

Adam G. Sevani Prior to acting he was one of the dancers in Missy Elliot's music video "I'm Really Hot."

In 2011 he starred alongside Miley Cyrus and Demi Moore in the movie “LOL.”

Sharni Vinson Starting at the age of twelve, Vinson trained for ten years at the Brent Street School of Performing Arts. From 2005 until 2008 this “Step Up 3D” cast member played Cassie Turner on the Australian television show “Home and Away.” Prior to playing Tara in “Step Up 3D” she guest starred in the American television shows, “Cold Cast" and "NCIS.” In 2011 she had a starring role in “Bait“ and the direct to video movie “Blue Crush 2.”

She played Sarah Baker, one of the Baker children, and in 2005 reprised the role in "Cheaper by the Dozen 2."
