As a production company, Hallmark ranks among the most popular for streaming releases, especially around the holidays. Where once they released a few seasonal movies, their Christmas films are now in the dozens annually, making them a lucrative way for actors to get their faces in front of fans who didn't expect to see them appear in a Hallmark film.

The relationship is certainly beneficial to Hallmark, as the draw of recognizable movie stars can mean even higher ratings for films that might ordinarily be overlooked due to predictable plots and tropes. Plenty of big names have lent their star power to a Hallmark film, and sometimes several!
