13 days ish of Halloween: Facts that you might not know about the original Night of the Living Dead movie.

The king of zombie flicks started out as an alien horror comedy about "hot-rodding" teens who would come to earth and create mischief with help from their pet called "The Mess".

After a series of rewrites and budgetary constraints, it turned into the beloved horror flick it is today.
The movie was made on a $150,000 budget.
Red ink or chocolate syrup was used for the blood.
For the scene in which Karen Cooper begins eating her father’s corpse, the crew’s leftover lunch was used.The actors were amateurs.
Three different crew members volunteered to have themselves set on fire to add realism to the movie.
There was one zombie who was nude, which caused a lot of attention from the citizens of Evans city, where the movie was shot.
Night of the Living Dead’s co-creators  Romero and

Russo both make cameos in the film. 

Russo played one of the ghouls who managed to reach into the farmhouse only to be struck with a tire iron.

Romero can be seen in the Washington D.C. sequences as a reporter.

The Walter Reade Organization, wanted to release it under the title Night of the Flesh Eaters, but lawyers representing the makers of 1964’s The Flesh Eaters threatened a lawsuit.

When the title was then changed to Night of the Living Dead, copyright notices were not added to the opening titles or to the end credits. 

Though the filmmakers have fought it in federal court, the film is still in the public domain.
