The "Serendipity" star will join Daniel Bruhl and Cara Delevingne in the fictionalized adaptation of Barbie Latza Nadeau's book "Angel Face: Sex, Murder and the Inside Story of Amanda Knox."
Published in 2010, the book is based on Latza's findings and it "describes how the Knox family’s heavy-handed efforts to control media coverage distorted the facts, inflamed an American audience, and painted an offensive, inaccurate picture of Italy’s justice system. An eye-opener for any parent considering sending a child away to study, Angel Face reveals what really went on in this incomprehensible crime."
Beckinsale will play a reporter investigating the crime surrounding Delevigne -- Knox's fictional counterpart -- while Bruhl plays a documentary filmmaker who is also investigating the case.
Paul Viragh will be in charge of the screenplay.
"The Face of an Angel" is due in theaters in 2014.
