Sir Alfred Joseph Hitchcock, (1899, London, England – 1980, Los Angeles, USA) was a director and producer of over 90 suspense and thriller movies. His career started in 1920th, from the silent film era, and lasted for six decades to the colour motion picture era.

He briefly appeared in all of his movies beginning with The Lodger (1927). In Lifeboat (1944) he, however, appeared on a picture in a newspaper advertisement for weight loss that floated among some debris around the boat. Around that time he had lost a considerable amount of weight from dieting, so he was seen in both the "Before" and the "After" pictures. All his life he was overweight, and was at his heaviest in the late 1930s with over 300 pounds (136 kg).

When Hitchcock was a kid, after acting childishly he was sent by his father sent him to the local police station carrying a note. After reading this note the police officer on duty locked him in a cell for about ten minutes. Later he cited this phobia as the reason he never learned to drive. Moreover, in almost every Hitchcock’s film, the police either have no impact at all, or mistake important clues, or let the culprit go.

He preferred blonde actresses and liked to insert in his movies the close-ups of woman's hairstyle. The most famous actresses in his filmography were Joan Fontaine, Ingrid Bergman, Grace Kelly, Kim Novak, and Tippi Hedren.

Hitchcock hated to shoot on location, and preferred to shoot at the studio where he could control lighting and other factors. He always wore a suit on film sets.

Hitchcock said that “if it's a good movie, the sound could go off and the audience would still have a perfectly clear idea of what was going on”, and that “the length of a film should be directly related to the endurance of the human bladder”.
