12 Men of Christmas
9/8c Lifetime
Kristin Chenoweth brings her perky star power to this 2009 light holiday romance, which takes E.J., a jobless New York PR exec, and plops her into God's country.

E.J. runs into resistance when her idea for a sexy calendar featuring the town's best local resource — its emergency rescue squad — doesn't sit well with the squad's leader (Josh Hopkins). But with E.J.'s determination (and Chenoweth's charm), it's clear that resisting this calendar girl is futile. — Rhoda Charles
