Alfred Hitchcock was a renowned film director known for suspenseful films like Psycho, Vertigo, and Rear Window. Some common features of Hitchcock's films included the use of dark shadows and lighting, bold opening titles with dark colored fonts, empty or isolated settings like buildings and outdoor spaces, and camera shots like medium shots and high angles that established the mysterious tone. Hitchcock often filmed at night and in black and white, creating a dark and tense style that was a signature of his filmmaking.
