Jaws (1975)

Hands down, Jaws is one of the most undeniable, most memorable movie posters of all time. It takes the most terrifying visual of the film and plasters it right on the poster, plain as day. The simplicity of the color palette along with the finely detailed illustration made this one immediately recognizable and imitated countless times. The sheer size of the shark as compared to the unknowing woman swimming above has kept me, and many others, out of the ocean for a long, long time.
