Although the film only took 28 days to film, it took 10 weeks to edit.

Friday the 13th takes place on TWO infamous days, June 13, 1958 and June 13, 1979.

Sally Field auditioned for the lead role of Alice Hardy, that eventually went to Adrienne King. Producers have said that it was King’s ability to scream like hell on earth that got her the part.

Despite what you may think, the body count for the horror classic is much less than any horror movie today, or action movie for that matter. Including that snake, it is 11 deaths.

When people recall the iconic theme song by Harry Manfredini, they often repeat it saying, “Chi, chi, chi, ha, ha, ha.” In fact, the composer said it is “Ki, ki, ki, ma, ma, ma” in reference to Jason saying Kill, kill, kill, Mom, Mom, Mom.”

Friday the 13th banked almost $40 million upon its initial release. Not bad for a film that only cost a half million to make!
