Lifetime has gathered big-name talent for the first two of its four upcoming movie adaptations of Nora Roberts novels, according to The Hollywood Reporter.

Emilie de Ravin, Ivan Sergei and Cybill Shepherd topline High Noon, while Jerry O'Connell, Lauren Stamile and Faye Dunaway lead the cast of Midnight Bayou.

The four Roberts adaptations, which also include Tribute and Northern Lights, are produced by Peter Gruber's Mandalay TV and Stephanie Germain Prods., the companies behind the four previous Roberts movies for Lifetime that scored big ratings in 2007.

In High Noon, written by Terri Kopp and to be directed by Peter Markle, hostage negotiator Lt. Phoebe McNamara (de Ravin) juggles her career with the demands of raising her young daughter and contending with her agoraphobic mother (Shepherd). Phoebe becomes the object of affection of a bar owner (Sergei) and the target of a psychopathic killer.

In Midnight Bayou, penned by Stephen Tolkin and to be directed by Ralph Hemecker, lawyer Declan Fitzpatrick (O'Connell) impulsively gives up his settled life to buy a newly restored -- and possibly haunted -- plantation manor near New Orleans. In the house, Declan begins to see visions from a century past and, with the help of a Cajun local (Stamile) and her grandmother (Dunaway), he uncovers a shocking secret.
