The cast for Oliver Parker's upcoming drama "Dorian Gray" is growing, and one of the latest to jump on board the project is Rebecca Hall, according to Variety.

Based on the classic Oscar Wilde novel "The Picture of Dorian Gray," the story centers on a young man (played by Ben Barnes) who becomes the subject of a painting. As the man embarks a quest for pleasure in life, the painting begins to morph and age.

Also starring in the adaptation is Colin Firth, who plays a ruthless aristocrat corrupting the titular character with his worldview. Ben Chaplin, Max Irons, Fiona Shaw and Emilia Fox co-star, among others.

Hall recently starred in Christopher Nolan's "The Prestige." She will next be seen alongside Scarlett Johansson in Woddy Allen's "Vicky Cristina Barcelona." Other upcoming projects include Ron Howard's "Frost/Nixon" and Charles Sturridge's "Brontë."

British actor Colin Firth has signed on to star opposite Ben Barnes in Oliver Parker’s “Dorian Gray,” an adaptation of Oscar Wilde’s classic novel “The Picture of Dorian Gray,” according to The Hollywood Reporter.

Barnes will play Dorian Gray, a young man who becomes the subject of a painting. As the man embarks on his quest for pleasure, the painting begins to change and age.

Firth is set to play Lord Henry Wotton, a ruthless aristocrat who corrupts Gray with his worldview.

Firth is currently onscreen in Universal’s “Mamma Mia!” He will next be seen alongside Uma Thurman in Griffin Dunne’s comedy “The Accidental Husband.”

Barnes is known best for his role as Prince Caspian in “The Chronicles of Narnia: Prince Caspian.” He also recently wrapped Stephan Elliott’s British comedy “Easy Virtue,” in which he stars opposite Jessica Biel and, coincidentally, Colin Firth.
