For those moving to Los Angeles from other cities and towns, the West Coast metropolis can require a bit of an adjustment period. But the secret to success is making sure not to judge a book by its cover, a lesson that fuels the romantic new Hallmark Channel Original Movie World Premiere “Perfect On Paper” Saturday, September 20 (9 p.m. ET/PT, 8C). The film features the incomparable Morgan Fairchild (“The Seduction,” “The Bold and the Beautiful”) as its marquee star, alongside soap opera darling Lindsay Hartley (“Passions,” “All My Children”). Fairchild portrays author Beverly Wilcox, a powerful, glamorous and intimidating figure straight out of “The Devil Wears Prada.” Our heroine in this tale of love and literature is Natalie Holland (Hartley), a book editor from Portland who unfortunately hasn’t had good luck in relationships. But when Natalie accepts a job offer from a publishing friend in Los Angeles, she finds herself moving to the West Coast metropolis and working alongside Beverly. As if that weren’t enough, more complications arise when she meets a handsome surfer (Drew Fuller of “Charmed”) and a charming, successful LA attorney (Kieren Hutchison of “One Tree Hill”). As tensions mount at work and in romance, the young editor learns a lesson about judging a book by its cover and finds out that guys who look “Perfect On Paper” may not always be the better choice.
