The most important reason Angela Kinsey was eager to take the plunge with “Confessions of a Christmas Letter,” her first Hallmark Christmas movie, was personal.

“I’m new to the Hallmark family, but I certainly have been a fan for a very long time,” said the actress best known as Angela Martin in “The Office” and for cohosting the “Office Ladies” podcast with Jenna Fischer which examines each episode of “The Office.”

“The reason I wanted to make this, honestly, my mom is 86 years old. She loves Hallmark Christmas movies! She had told me one time, ‘Are you ever going to play someone who’s not grumpy? (I’m ‘The Office’ grump.)

“When I got this script, I knew how tickled she would be. Plus, I just liked the script and thought it would be fun. At this time of year you can get stressed out during the holiday season. So if this movie reminds us all not to sweat the small stuff, that you don’t have to be perfect, and should love your family just as they are, that’s a great message I could get behind.”

“Confessions” is, not surprisingly, all about Christmas, Christmas traditions, Christmas decorations, Christmas meals.

“It’s about a Christmas letter writing competition in a small town where the winner gets their picture up at the small town post office. Which,” she said with a laugh, “are very high stakes in a small town.

“My character is lousy at writing Christmas letters. So she hires a novelist to write her Christmas letter. And, of course, really fun Christmas hijinks ensue.”

The hijnks spotlight the blocked author who hopes being paid to write will unblock his creativity. Only he’s still unhappy and far from home.  He keeps saying, ‘You’ve brought me here to write a Christmas card!’ and everyone has to say, ‘No, it’s a Christmas letter.’”

At this point it might be good to ask: What is a Christmas letter?

“Okay,” Kinsey, 53, began, “for those of you who’ve never received a Christmas letter (I get them every year), basically, you write an overview of that year and that family’s life.

“Someone will write a Christmas letter that will tell you what everyone was up to, who graduated from college, who got married, what happened.

“I love getting them, but there are one or two people who sometimes in their Christmas letter, maybe embellish their family’s accomplishments. My character is definitely one of those people.

“She wants her family to sound just a little bit more accomplished and maybe fancier than they are. Ultimately, she realizes that they’re great, just the way they are.

“They don’t have to have it all together.”

“Confessions of a Christmas Letter” airs on Hallmark Channel Nov. 17
