"This movie is so important because I'm part of the progress, and it feels good," he told ET's Lauren Zima. "I can only imagine what younger me would have thought seeing a Christmas movie with a storyline like this; two men in love, having a baby together. I think I would have been so excited, and I know I'm excited."
"Representation is so important, and to represent this storyline on Hallmark Channel, it's an honor to make a little history," he noted.
The Christmas House follows Brandon Mitchell (Bennett), and his husband Jake (Harder), who make a trip home for the holidays as they anxiously await a call about the adoption of their first child.
"When I read the script, I got so excited that we [were] going to get to go and make this movie but also for the younger Jonathans out there watching it," Bennett expressed. "To see a movie like that, where you see yourself on screen is so important and I think this Christmas younger me is going to be a little bit less scared and feel a little more seen. Especially with what's going on in 2020, this is going to be a little bit of hope and a little bit of love that everyone can watch."
Bennett said adopting is something that he and his partner, Jaymes Vaughan, have spoken about.
"We're thinking about that for sure, especially shooting this movie it really spoke to me," he said of expanding their family. "It's almost like life imitates art. You get to set and you watch this couple in the movie going through the adoption process and there's highs and there are lows in that and there's everything in between. But during one of the scenes where we kind of have a little tiff, you see a couple come together and surround each other with unconditional love."
"And that's when I realized, 'Wow, this movie's so important because it's showing that unconditional love that a couple has for each other when all they want to do is start their own family…and create more love for everyone,'" he continued. "That scene and having this in the movie definitely made me feel like maybe, I think, we might need to do that at some point."
Above all else, Bennett couldn't be more grateful to be part of this historic film for the Hallmark Channel, and hopes that people feel seen and part of the family.
"I just wanna say, from the bottom of my heart, I am so proud of Hallmark Channel and everyone there for doing what they did this year, which was taking the holiday table and making it bigger and more welcoming than ever," he concluded. "I think so many people are gonna feel seen and so many people are gonna feel like they belong in the Hallmark family -- and they do. It's gonna be a really special year for so many people."
The Christmas House premieres Sunday, Nov. 22 on the Hallmark Channel.
