Charles Laughton excels as local grandee "Sir Humphrey" in this super adaptation of Daphné du Maurier's book. The bleak photography and huge great waves help generate a sense of the menace of the evil Cornish wreckers. They are led by Leslie Banks's malevolent "Joss" who is just as cruel to his wife "Patience" (Marie Ney) as he is to any survivors after his men seek to drive ships onto the rocks and make off with the contraband - murdering as they go. His niece "Mary" (Maureen O'Hara) and under-cover customs man "Trehearne" (Robert Newton) discover the evil antics and complicities of both "Joss", his puppet-master and his accomplices and the film now tells the tale of their own death-defying actions trying to bring all to justice. Alfred Hitchcock has much to work with here, the photography is effective and the star is exactly that.
