Today has been kind to Alfred Hitchcock and the Making of Psycho. Just a few hours after the semi-biopic nabbed Jessica Biel for a movie star role, Variety reports that a strong quartet of actors are about to dot their name on the contract line. Who, you may ask? Michael Stuhlbarg, Toni Collette, Danny Huston, and Michael Wincott, all of whom will take up historical personas big and small.

Stuhlbarg has been tapped to play Lew Wasserman, then-agent to Hitchcock and, you may or may not know, future head of Universal Studios; Collette will be seen as Peggy Robertson, the Master of Suspense’s “fiercely protective” assistant; Huston is Whitfield Cook, friend to Hitchcock’s wife, Alma (Helen Mirren), and co-writer of Stage Fright; and Wincott has the most interesting role: Ed Gein, the infamous serial killer who partly inspired the character of Norman Bates. (And Leatherface, while we’re at it.)

Sacha Gervasi‘s directing, while Anthony Hopkins will take center stage in a film which, above all else, depicts struggles with budget and reputation that plagued Hitchcock during the (what else?) making of his 1960 horror masterpiece. Scarlett Johansson and James D’Arcy will also chip in, playing Janet Leigh and Anthony Perkins, respectively; I’d expect more casting of this nature to come our way very soon. Production is expected to kick off in the next couple of months.

Do these casting additions inspire further confidence when it comes to The Making of Psycho?
