Few film-makers have been analysed as extensively as Alfred Hitchcock. Films such as I Confess, Under Capricorn, The Wrong Man and Marnie deal with questions of sin, forgiveness, conscience and grace. While I Confess remains Hitchcock’s most explicitly Catholic film, religious themes are present in the innocent suffering and prayer of The Wrong Man and in the guilt and redemption of Vertigo and Marnie. These films reflected concerns shaped by his upbringing and remained visible throughout his career.
