Savage said that at the time, he and the former "Dancing with the Stars" competitor were only 11 or 12 at the time. McKellar added that the shoot came with a mix of emotions.
"It was really nerve-racking because there's 50 people standing around watching you," she said. "Now, the one upside of having your first kiss on camera is that you know for sure that it's gonna happen. You don't have to wonder! The downside is that you have an audience, so that was crazy."
It took the young actors six takes to get it right.
McKellar said that her grin made the first attempt unusable.
"In the story my brother's just died so I'm supposed to be really sad but I got so excited that I got this smile on my face!" she said. "The one you see is take number six... and the reason I know it was the last take is because on the last take Fred started to stroke my hair afterwards. That's the only time they did it and that's the one they used."
