The appearance of actors in a movie poster should never, ever argue with how they look in the film itself. Violation #1: Julie Christie‘s wig in Shampoo is straight, thick and frosty blonde — her natural poster hair is blonde-brownish and curly. Violation #2: In the film Goldie Hawn‘s blonde hair is worn with bangs — in the poster it’s oddly parted in a slightly off-center fashion. Violation #3: In the poster Warren Beatty‘s hair is noticably shorter than it is in the film.
