Without Warning

Without Warning, which is also known as It Came... Without Warning and Alien Shock, is a 1980 science fiction horror film starring Jack Palance, Martin Landau, Tarah Nutter, and Kevin Peter Hall, directed by Greydon Clark. Special effects designer Greg Cannom, who was later involved in major studio productions such as Jurassic Park, Hook and Titanic, created the aliens for this low-budget film. The film released on September 26, 1980 and was released on home video for the first time on August 5, 2014 through Shout! Factory's Scream Factory label in a Blu-ray/DVD Combo Pack. Without Warning is credited with being an inspiration for the 1987 film Predator, both of which starred Kevin Peter Hall as a costumed alien hunter.
