pros dont steal.. they "Reference".
It's still steeling according to how I see it.
At UCF, in my film classes, I met Edward Sanchaz. He was also the president of the UCF Cinematographer Association, which I was a member. He had the club produce a short film about someone winning the lottery at a cost of tens of thousands of dollars from money he got from his family. A girl (named Kate) I was friendly with who was in my screenwriting classes and the club worked after school every day helping him edit it the project. He transferred to USC (University of Southern California) the following semester. A few years later, I see his name all over the news and media for writing, producing, and directing the Blair Witch Project. He even used the same troupe of improv actors who from Orlando (who were unknown).
I remember he had the idea for Blair Witch even when he was at UCF. He had this idea of not fully developing the script, but having a vague outline and having improv actors fill in the rest spontaneously on the set. If you look at the acting credits, you will see that the names of the actors and the same names as the characters they play. This was intentional because some of the scariest moments in the movie were not acting. Ed had a sick sense of humor. He played practical jokes with the actors. In one scene, a character wigs out because she sees a dead bird or something to that effect. The truth is that they really used a dead bird and failed to tell the actors this. So, the reaction you see from the character is really the actress freaking out the she wasn't told a dead bird was going to be used. That was just the beginning of pranks Ed would use on the cast. After a while, they just got fed up with it and wanted to quit. By then, Ed had apologized and said he was ready to call it a day, but there was a problem. He was lost (so he claimed). When he broke the news to them of being lost, he made sure he cameras were on. A real melt down took place, with the actors absolutely furious. That meltdown was used as actual footage. Of course, after all the tears and a super "performance", Ed turned off the camera and told them he wasn't really lost.
The whole first person style and of Steady Cam was never done before Blair Witch. That style is still being copied over and over again. To me, that's steeling. Can't film makers be original? Why are new films being produced that are still trying to copy what he did? No matter how much they try to copy, notice none come out as good. It's because of those "other" things Ed did, which, by the way, is very morally questionable.
The name of my final screenplay project for the class we shared was The Utopian Project. In class, we would read over every 20 pages (of around 100 pages) we wrote at a time to the class (which had just 10 people in it) and then have a group discussion about it. He was well familiar with the name of my script. I wonder if this stuck in his head when he named Blair Witch as Blair Witch Project...
There's a lesson about originality and copying ("steeling") somewhere in this post if you look hard enough.
Oh, and my screenplay for that class was the best. No other work held so much attention with such suspense and wanted reactions than my script did!
