EXCLUSIVE: Lifetime is developing a movie about the highly-publicized case of two couples involved in an IVF mix-up. Sony Pictures TV, which is producing the project, has acquired the rights to the story of Carolyn and Sean Savage and Shannon and Paul Morrell, who made headlines when a fertility clinic mistakenly implanted the Morrells’ embryo into Carolyn Savage. Savage went on to give birth to a baby boy, which was then given to the other couple.

Nancey Silvers, who most recently wrote Lifetime’s upcoming movie William and Kate, will write the telefilm, which is based on Carolyn and Sean Savage’s book Inconceivable, released today by Harper Collins, as well as Shannon and Paul Morrell’s book Misconception published last spring and released in paperback 2 weeks ago. The Savages were on the Today Show this morning promoting the book, and their case was also featured on Dateline NBC on Friday. Executive producing the movie are Alan Gasmer, Clark Peterson, Judith Verno, Ron Senkowski and Mary Martin.
