This year marks the 40th anniversary of the theatrical release of Alien, the 1979 scifi/horror masterpiece from director Ridley Scott, starring Sigourney Weaver, Tom Skerritt, Harry Dean Stanton, Veronica Cartwright, John Hurt, Ian Holm, and Yaphet Kotto. Now, Fathom Events, TCM, and Twentieth Century Fox are bringing the film back to theaters nationwide for 3 days only this month.

Theaters nationwide will be showing the film on October 13, 15, and 16, as part of TCM’s Big Screen Classics Series. The screenings will include special commentary before and after the film from TCM Primetime Host Ben Mankiewicz, as well as an introduction with newly unearthed and rarely seen alternate takes.
