Rob Lowe has signed on to star in an upcoming Lifetime Original Movie, with the working title "Prosecuting Casey Anthony," as Florida prosecutor Jeff Ashton.

The movie will follow the highly controversial murder trial of Caylee Anthony and is based on Ashton's best-selling book, "Imperfect Justice: Prosecuting Casey Anthony."

On July 5, 2011, Casey Anthony was acquitted of killing her 2-year-old daughter Caylee, despite what was considered by many to be overwhelming evidence of her guilt. The movie will be shown in Ashton's (Lowe) perspective and will follow the investigation into Caylee's death and the ensuing trial.

Lowe previously appeared in the Lifetime Original Movie, "Drew Peterson: Untouchable," which followed the story of Drew Peterson, a man who was charged with the death of his third wife after the disappearance of his fourth wife, Stacy Peterson (Kaley Cuoco).

"Happy to follow up on the success of "Untouchable" with "Imperfect Justice" Playing the first prosecutor to use DNA to get a conviction," Lowe Tweeted on May 4, adding, "Superior conviction record, then Casey Anthony. What went wrong? A hard look at our modern justice system."

"We're thrilled to have Rob returning to our network, after his amazing star turn as Drew Peterson," Lifetime's Executive Vice President of Programming Rob Sharenow said in a statement. "He's one of those rare stars who can do it all, comedy, drama, heroes and villains. There are very few actors in the history of our business who have been able to have such success on such a broad range."

The 48-year-old actor currently stars in NBC's comedy "Parks and Recreation" as Chris Traeger, the overly-enthusiastic health-obsessed interim Pawnee city manager. Lowe also recently guest-starred on the fourth season of the Showtime series "Californication" as Eddie Nero, an actor who wants to play the role of David Duchovney's Hank Moody in a movie adaptation of his book. Lowe left the ABC drama series "Brothers & Sisters" after the May finale of its fourth season after starring as regular cast member Robert McCallister.

Lowe began his acting career in the late 1970s, starring in the show "A New Kind of Family" and "ABC Afterschool Specials." He later went on to play bad boy Billy Hicks in the cult 1985 film "St. Elmo's Fire" with the "Brat Pack" of the 1980s, which includes Emilio Estevez, Judd Nelson, Demi Moore and Ally Sheedy.

Lowe also played a villain in the comedy films in "Wayne's World" in 1992 and "Tommy Boy" in 1995. About a decade ago, he returned to television and played Sam Seaborn in the Emmy-winning series "The West Wing" and Dr. Billy Grant in "Dr. Vegas."

The Lifetime Network previously documented another controversial murder trial with "Amanda Knox: Murder on Trial in Italy," which starred Hayden Panettiere as American student Amanda Knox, who was jailed in connection with the murder of her roommate in the Italian city of Perugia.
