It Conquered the World (1956). Monster built by Paul Blaisdell. Blaisdell originally constructed the thing to end above the eyebrows, reasoning that the heat and pressure of Venus would result in a squatty little monster. The director, upon seeing the heroine confront a monster half her height, wanted more monster... hence the "space cucumber" look, as Blaisdell simply added a big pointy top to the whole critter.
