What character did Michelle Trachtenberg play in the 2005 movie "Ice Princess"?

Michelle Trachtenberg played Casey Carlyle in the 2005 movie Ice Princess.

Casey is a highly intelligent high-school student whose academic goal is to win a scholarship to Harvard. While working on a physics project, she applies mathematics to figure skating and discovers that the sport she once treated as a hobby could become her true passion. Her story follows the tension between meeting other people’s expectations and choosing a dream for herself.

The film combines teen comedy, family drama, and sports storytelling. Casey’s mother, Joan, initially pushes her toward an academic future, while Casey becomes increasingly committed to competitive skating. The movie also features Kim Cattrall, Joan Cusack, Hayden Panettiere, and Trevor Blumas, with Tim Fywell directing.

A common mix-up is confusing Casey Carlyle with the other young skaters in the film, especially Gen Harwood, played by Hayden Panettiere. Casey is the central character and the one whose skating journey is driven by a physics-based school project. Ice Princess was released by Walt Disney Pictures in March 2005.
