Planning on celebrating Halloween with a plethora of zombie films? If you find yourself running short on some of the legendary zombie classics out there, get on the internet and watch FilmOn’s Zombie Underworld channel for free.

Zombie Underworld airs only classic zombie films 24 hours a day, meaning that you’ll be able to live in zombie terror whenever you want. One of the films you can watch on Zombie Underworld is the film that is considered the Holy Grail of zombie films, “Night of the Living Dead.”

“A group of individuals from various walks of life find themselves barricaded in a rural farmhouse. In an attempt to survive the night from the hordes of relentless blood-thirsty zombies outside, the group will do everything they can. They eventually find out that the only thing that can stop these zombies is a gunshot or heavy blow to the head.”

Another film on the roster is “Revolt of the Zombies,” which puts zombies in the time of WWI.

“An WWI frontier is condemned to life imprisonment because he possesses the power to turn men into zombies. While in prison, the frontier is killed and the secret location to the formula to his secret power is stolen.”

You can watch Zombie Underworld below the post or at its page on FilmOn. FilmOn offers tons of channels for free in SD or, for a low monthly subscription, in HD with added DVR recording space.
