Elisabeth Moss assists 'Morgans' film

Actress cast opposite Sarah Jessica Parker, Hugh Grant

Elisabeth Moss, one of the stars of "Mad Men," has been cast opposite Sarah Jessica Parker and Hugh Grant in "Did You Hear About the Morgans?" Marc Lawrence's romantic comedy for Columbia Pictures.

Parker and Grant are starring as an estranged high-powered New York couple who witness a murder and are placed in a witness-protection program in a small Wyoming town.

Moss will play Parker's executive assistant with a controlling and almost obsessive-compulsive personality.

Lawrence will be directing from his own script, which previously was untitled, with Liz Glotzer and Martin Shafer producing. Production is set to begin in May in New York.

The project is Moss' first feature role since appearing in AMC's awards darling "Mad Men." She was nominated for a 2009 SAG Award for outstanding performance by a female actor (drama) for her role as naive new girl-turned-savvy office player Peggy Olson.

Featurewise, Moss was nominated for a best actress Spirit Award for 2003's "Virgin" and appeared in movies including "Girl, Interrupted," "The Missing" and "Mumford."

Moss, repped by Endeavor and manager Gay Ribisi, made her Broadway debut last year in David Mamet's "Speed-the-Plow," which ended its run Feb. 22.
