Producing dozens of films a year, Hallmark Channel is known for keeping its movies within its own circle of stars — which is why you can find the Queen of Hallmark Lacey Chabert in over 30 romance and Countdown to Christmas flicks. But often, the actors you see in these romcoms were once known for sitcoms.
