In 1976, Brian DePalma directed a movie version of Stephen King’s first book, and we all watched it and then went home and hid under the covers for a week or so. Those of us of a certain age know the plot of Carrie by heart, but there are a few things that went on behind the scenes that you might not know. For example,
4. KING’S NAME WAS MISSPELLED IN THE TRAILER.
King was such a newcomer at the time of Carrie's release his first name was actually misspelled in the movie's trailer (it was written as Steven, not Stephen).
5. THE STARS OF CARRIE COULD HAVE BEEN THE STARS OF STAR WARS.
Brian De Palma ended up casting for Carrie at the same time his good friend George Lucas was doing the same for a little sci-fi film he was making called Star Wars. So the two made the rather unorthodox decision to hold joint auditions, which ended up becoming a bit confusing. De Palma liked Amy Irving for the lead in Carrie, but she was also considered for Princess Leia in Star Wars. William Katt also auditioned for Star Wars, alongside Kurt Russell.
You can see those auditions, along with plenty of other tidbits about the making of the original Carrie at mental_floss.
