Though the warm weather made the idea of jumping into a lake much more appealing, it ended up being a scene that Sarah Drew didn't feel prepared for in the film. "I got really nervous as the moment was approaching," she admitted.

When Drew was writing the film's polar bear plunge scene, she knew it would be an exciting one to see on screen. "You don't get big action sequences in Christmas movies, usually," she told The List. "I thought it would be really fun."

Yet, as exhilarating as it sounded, it never crossed her mind that she would be the one depicting the spine-chilling scene as the film's star. She also hadn't yet come to the realization that she would also be in a swimsuit in front of thousands of households. When the director called action, the actress got anxious to run into the water. "Justin [Bruening] was like, 'You've got this, you've got this,'" Drew explained. "He was doing the opposite of what my character was doing for him."

After a few takes of repeatedly jumping into the water, Drew eventually conquered her fear of the cold. "It's a mind-over-matter thing," she laughed. "You're like, 'Okay, this is my experience now. There's no way I can't do this. I wrote it. I must.'"
