‘The Groomsmen’ trilogy 

Hallmark built on the success of its popular Wedding Veil movies, which followed the interconnected stories of a trio of friends, with The Groomsmen trilogy. The three movies – which focus on three best friends from different backgrounds and cultures as they come together to celebrate their wedding days – premiered on Hallmark+ last year. Now, they’re making their way to Hallmark Channel. 

The Groomsmen: First Look stars B.J. Britt and Heather Hemmens as a pediatrician and an overseas doctor who meet at a wedding in Philadelphia. Unfortunately, long distance, family, and their friends hinder their budding romance. It airs Saturday, September 6 at 8 p.m. ET/PT. 

The Groomsmen: Second Chances stars Jonathan Bennett as Danny, who has been hiding his romantic feelings for his best friend (Alexander Lincoln). He finds the courage to confess after he is asked to be the best man at his wedding in Greece. It airs Saturday, September 13 at 8 p.m. ET/PT. 

The Groomsmen: Last Dance follows Jackson (Tyler Hynes) who movies to Italy to be near his daughter. There, a chance meeting with a cafe owner (Elena Rusconi), plus some meddling friends, may lead to a second chance at love. It airs Saturday, September 20 at 8 p.m. ET/PT.

‘Adventures in Love and Birding’ 

Hallmark’s newest rom-com is an adaptation of Sarah T. Dubb’s best-selling novel Birding With Benefits. It stars Rachel Boston as a single mom who agrees to be a bird enthusiast’s (Andrew Walker) partner during a birding tournament. But she misunderstands the assignment and tells everyone she’s his girlfriend instead of his teammate. 

“This is just absolutely surreal, and I don’t even know what to say about it!” Dubb wrote on Instagram after the movie was announced. “I’m honored that the folks at Hallmark were drawn to this story, and I hope they make a movie that makes lots of people happy and maybe even makes them want to go birding!”
