Dakota Fanning is doubling down on Showtime roles.

The Alienist: Angel of Darkness and Once Upon a Time in Hollywood actress is joining drama Ripley opposite Andrew Scott.

It comes after she was cast in Showtime’s scripted anthology drama series The First Lady (w/t) as Susan Elizabeth Ford, the only daughter and youngest child of President Gerald and Betty Ford.

In Ripley, Fanning will play Marge Sherwood, an American living in Italy who suspects darker motives underlie the affability of Tom Ripley, played by Fleabag star Scott.

Based on Patricia Highsmith’s books, the show comes from The Night Of’s Steven Zaillian.

The series follows Tom Ripley, a grifter scraping by in early 1960s New York, who is hired by a wealthy man to try to convince his vagabond son, Dickie Greenleaf (Johnny Flynn), who is living a comfortable, trust-funded ex-pat life in Italy, to return home. Tom’s acceptance of the job is the first step into a complex life of deceit, fraud and murder.
