Helen Mirren has joined the cast of Alfred Hitchcock and the Making of Psycho, a project which has moved from Paramount Pictures to Fox Searchlight.

We reported in January that actor Anthony Hopkins will portray Alfred Hitchcock in this dramatic comedy, which is adapted from Stephen Rebello's non-fiction book of the same name. Helen Mirren will play the director's wife, Alma Reville, in thus project that focuses on Alfred Hitchcock's quest to make his 1960 horror classic Psycho, which no studio wanted a part of at the time. The adaptation focuses on how Alfred Hitchcock secured financing himself, as well as the filmmaker's relationship with his wife.

Sacha Gervasi (Anvil! the Story of Anvil) is directing Alfred Hitchcock and the Making of Psycho from a screenplay by John J. McLaughlin (Black Swan) and author Stephen Rebello. An April production start date is being eyed by the studio.
