Alfred Hitchcock is going psycho when movie audiences use their cell phones in theaters. To help promote the upcoming biographical drama ‘Hitchcock,’ Anthony Hopkins, who portrays the notorious filmmaker in the film, has recorded a PSA to help put an end to the madness.

‘Hitchcock,’ which is based on the book ‘Alfred Hitchcock and the Making of Psycho’ by Stephen Rebello, opens in select theaters on November 23. The film, which was directed by Sacha Gervasi and written by John J. McLaughlin, tells the love story of one of the most influential filmmakers of the last century, Alfred Hitchcock, and his wife and partner, Alma Reville. The movie takes place during the making of ‘Psycho.’

Watch the PSA below.
