Blumas ended up playing Teddy as a sort of father figure. He began training to drive a Zamboni soon after arriving in Toronto; according to him, he later ended up smoothing the ice on some mornings at the rink where they were shooting. Panettiere did much of her own skating, including a fast spin seen at the end of the regionals short program. Trachtenberg trained for eight months, including the time they were filming (during which time she says she worked twenty-hour days). She had to be on the ice longer than most of the other actors as she was one of the few adults on the film. She had stunt doubles to handle the falls and some of the complex moves, although Trachtenberg did learn a specific move that could not be done by a stunt double as the differences in their build would be apparent. She sustained some injuries while working on the film. According to Trachtenberg, a mistake was made in one of the physics formulas her character recites, which was later fixed; a shot of the back of her head was used and the correct term was looped in. Trachtenberg described the film as ``not a Disney kitschy movie'' and was somewhat apprehensive of the idea of a sequel for fear of belittling the original. Cusack noted that the relationship between Casey and her mother had already been well-developed in the script, but said that it generated a good deal of discussion during the production, and Cusack ultimately described her role as ``meaningful'' in terms of the acting and also how it related to her personally.

Tara struggles against Gemma's beating and her head is badly smashed on the sink, where Gemma then attempts to drown her. In one of the show's most gruesome moments, Tara struggles for several seconds before Gemma grabs a barbecue fork and stabs Tara multiple times in the back of the head and her neck.
