Rambin had a lead role in the fantasy film "" (2013), playing Clarisse La Rue, a hot-tempered, arrogant, large, and strong demigod (also the lead counselor of the Ares Cabin 5) and Percy's rival throughout the story. In an interview with "comingsoon.net", Rambin explained her casting and her time as a brunette, "Yeah, I was really lucky that Thor was able to see me as a brunette with this blonde hair. That's not typically the first thing that comes to mind when you look at me, I don't think. But when I put on that wig – luckily they didn't dye my hair – and change my physicality a lot... Nothing against brunettes – I still felt beautiful. But I felt a lot less inhibited, and I felt down to be a little more brash and powerful and strong. I kind of hid behind all this brown hair, and it gave me the power and confidence to verbally rip this one over here. [Laughs.]" Her portrayal as Clarisse was met with mostly positive reviews. In 2013, Rambin moved to New York City to study acting full-time at the Playhouse West Brooklyn Lab and is now a teacher and staff member at the school.
