After finding hit movie material in the book “How to Lose a Guy in 10 Days,” Paramount Pictures is going back to the relationship shelf.

Par-based producer Carsey-Werner-Mandabach has optioned Rachel Greenwald’s “Find a Husband After 35 Using What I Learned at Harvard Business School,” which will be published Sept. 16 by Ballantine. The title will be shortened and scriptwriter Claudia Lonow will use the instructional manual as the basis for a romantic comedy.

Greenwald certainly seems to know a lot about helping thirtysomethings hook hubbies. The holder of an MBA from Harvard, she is the “Love Over 40” advice columnist on msn.com, runs seminars for the lovelorn and works as a private dating coach.

Producer Caryn Mandabach said the book figures prominently in the film’s premise.

“We will focus on a group of women who read the book and try to tap the formula to find mates,” she said. “We think that this will tap into something very rich and in the zeitgeist right now.”

Lonow is the creator of the Showtime series “Rude Awakening,” and is consulting producer on ABC series “Less Than Perfect.”

She also created and exec produced the Oxygen-based pilot “My Roommate Is a Big Fat Slut.” That series is being done by Carsey-Werner-Mandabach.

Lonow sparked to the “Find a Husband” book and gave it to CWM, which made the deal through its Paramount feature pact. ICM put the deal together.
