Awhile back, Jenna wrote in her MySpace blog about working on the film:
Over the summer I worked on the comedy “Blades of Glory” with Will Ferrell, Jon Heder, Amy Poehler, Will Arnett and Romany Malco. On my first day of shooting I had to do a scene with Will Arnett and Amy Poehler (they are awesome). I don’t want to give away any jokes but basically I play their little sister and they are really mean to me throughout the movie. At the end of our first scene together the camera holds on my reaction and for the first 2 takes I looked into the camera.
