Scottie Thompson teams up with Kathy Najimy for the (surprisingly funny) new holiday thriller!

With credits like NCIS and Trauma under her belt, Scottie Thompson is used to kicking butt and taking names — but she tells HollywoodLife.com that her next assignment is a bit “less harrowing” than she’s accustomed to. In TNT’s Deck the Halls, premiering Dec. 20 at 9 p.m., she plays Regan Reilly, a detective whose father has been kidnapped during the holidays. ”It’s a Christmas story that gives you a bit of a scare to remind you the important part of the holiday is family,” she says.

The lighter side of the story comes courtesy of Kathy Najimy, a cleaning-woman-turned-private-eye who teams up with Scottie’s character to track down her father.

“It was a ton of fun,” Scottie says of working with Kathy. “She’s so talented.”

And part of the reason Scottie loved acting alongside a comedy icon like Kathy was because she hopes to branch out in her own career.

“I really want to get into more comedy,” Scottie admits. “And while this story didn’t quite pave the way for that, the relationship between my character and Kathy’s character certainly allowed for a few of those moments. I really appreciated that.”

And trust us, you’ll appreciate them too.

Deck the Halls premieres Dec. 20 at 9 p.m. on TNT.
