Hallmark is staging a One Tree Hill reunion!

Chad Michael Murray, who played Lucas Scott for six seasons of the 2000s teen drama, and Torrey DeVitto, who portrayed nanny Carrie, are reuniting for an upcoming Hallmark Channel Christmas movie to premiere during the holiday season later this year, ET has exclusively learned.

Drew Seeley, who guest starred as mutual friend Vegas on One Tree HillLolita Davidovich and Grant Show also star in the original film, titled Five Cards for Christmas. Production kicks off next week.

The film's To All the Boys I've Loved Before-esque premise revolves around the recently single Jessica (DeVitto), who sends Christmas cards to five people who have impacted her life: the aunt (Davidovich) who raised her, her younger brother in the military, a pop star Jax (Seeley) who provided the soundtrack to her life, the music teacher who inspired her and her best friend, Mimi, who always tells her the truth. 

DeVitto's Jessica owns a music store and is a cellist, though she hasn't played in quite some time. Through a connection her best friend has at the philharmonic, she scores Jessica an audition, who reluctantly agrees to give it a shot and has only a week to dust off the rust.

Murray will play Luke, the son of Jessica's music teacher, who is one of the recipients of her cards. With the teacher out of the country, Luke is the one who opens Jessica's card. They have a chance meeting when Luke goes to Jessica's apartment to let her know in person how much the card meant to his mother.

Seeley plays Jax, a former pop star who receives one of Jessica's cards. In the card, she reveals his music helped her through a difficult time in her life. 

Murray (2018's Road to Christmas), DeVitto (2014's Best Christmas Party Ever), Seeley (2018's A Christmas for the Books) and Davidovich (2018's Once Upon a Christmas Miracle) have all previously starred in holiday movies for Hallmark. Show makes his Hallmark debut with this movie.

This isn't the only One Tree Hill reunion to take place onscreen in recent memory. Last year, Lifetime reunited Hilarie Burton, Robert Buckley, Danneel Ackles and Antwon Tanner for the original holiday movie, The Christmas Contract.

Hallmark is knee-deep in lining up its original holiday movies this year, as it celebrates its 10th anniversary of Countdown to Christmas. Earlier this year Hallmark banked its first Christmas film, The Christmas Song, starring Kristen Chenoweth and Scott Wolf, and has cast Legacies star Matthew Davis in another. While 2018 saw a record-breaking 38 Christmas movies, Hallmark will top that with 40 this year. 

"I think that our challenge to our team is to find casts that we haven't worked with yet," Michelle Vicary, Executive VP of Programming and Network Publicity at Crown Media Family Networks, told ET in February, adding that it's important to "continue to deliver on the brand and do more of what we do and make people feel good and make them want to buy socks and mugs and decorate their towns like a Hallmark Christmas movie. Someone said it to me the other day that Hallmark is a movement for people that want to feel positive and so, we are here to be bigger and bolder in that way."
