Lifetime is currently developing "Imperfect Justice," a movie about Casey Anthony, who was found not guilty of murdering her 2-year-old daughter, Caylee. And now comes word that the network has cast relative newcomer Holly Deveaux to play Casey. Deveaux is 19-years-old and has appeared in TV programs "Less Than Kind" and "Baxter" in Canada, as well as in a made-for-tv movie "Silent Witness," opposite Anne Heche and Dermot Mulroney. Other actresses considered for the role were Alyssa Milano and Jennifer Love Hewitt. The new movie will focus on the attorneys behind the controversial 2011 trial. It will co-star Rob Lowe as Jeff Ashton (the prosecuting attorney), Elizabeth Mitchell as Linda Drake Burdick (fellow prosecutor) and Oscar Nunez ("The Office") as Jose Baez (Anthony's defense attorney).
