David Fincher has famously disowned the film, citing constant studio interference from 20th Century Fox.

In 2003, a significantly different version was released. While not a "Director's Cut," it restores over 30 minutes of footage, changes the Alien's host, and is widely considered by critics at Rotten Tomatoes and fans to be a superior, more coherent version of the story. 4. Technical Achievements

Directed by David Fincher in his feature debut, is the third installment in the Alien franchise. It is well-known for its notoriously troubled production and its bold, polarizing decision to kill off major characters from the previous film, Aliens . 1. Plot Synopsis

The inmates have formed a fundamentalist religious cult, viewing the Alien as a "beast" sent to test or punish them.

The project went through numerous iterations, including a famous version by William Gibson set on a wooden space station inhabited by monks.

Ellen Ripley is the sole survivor of the crash, as Newt and Corporal Hicks are killed in the impact. Unknown to Ripley, an Alien facehugger survived the journey. The creature gestates within an animal (a dog in the theatrical cut, an ox in the assembly cut), giving birth to a "Runner" Alien that begins picking off the unarmed prisoners in the labyrinthine facility.

Immediately following the events of Aliens , a fire aboard the spacecraft Sulaco causes an escape pod to crash-land on , a desolate refinery and "blast furnace" inhabited by a colony of male inmates with a "Double-Y" chromosome mutation.
