Kirk Jones ("Waking Ned Devine," and "Nanny McPhee,") will direct the film adaptation of the pregnancy manual "What to Expect When You're Expecting," Lionsgate 
announced Wednesday.
The book — which wil be adapted into a romantic comedy — has been a New York Times bestseller for more than 500 weeks.
The writer Heather Hach ("Freaky Friday") pitched the film based on Heidi Murkoff's book.
"Black Swan" producers Mike Medavoy and Arnold Messer, along with David Thwaites, are producing and Doug McKay is co-producing through their Phoenix Pictures.
Heidi and Erik Murkoff will executive produce, as will their literary manager, Alan Nevins of Renaissance Literary & Talent.
