As with all storytelling techniques, I love it when done well and not otherwise.
"Star Wars" was neither "Episode IV" nor "A New Hope" when initially released. Those got added later:
You are certainly right that "in medias res" as a storytelling device goes way back. Homer's Odyssey a case in point. Even the original concept for" Star Wars" was designed with that in mind, as Lucas' plan was for nine films (which eventually happened). Subsequently, "Star Wars"was eventually given its original subtitle "Episode IV: A New Hope", and thus, the" Star Wars" saga does indeed begin "in the midst of things". However, starting out in the middle of the story is not the same as beginning with the end which was the point the original poster was making.
The ads [...] didn't give away the actual conclusion, but they revealed like 85% of the movie's story - maybe more.
And I think "WLB" and "Castaway" were the same.
As to the original post, I was a bit shocked at how simplistic and forest for the trees it was, especially in a forum like this.
The trailer for Castaway was infuriating. The trailer leaves no suspense for the viewer for nearly the whole movie while he's stranded. From the trailer we know he's saved, so for most of the movie you sit there with no feelings of danger, suspense etc. ...survival's assured. Ho hum.
Does anyone remember the American remake of RASHOMON called THE OUTRAGE? We screened it where I was working. It had a star-studded cast incl Paul Newman.
Even if the name of the movie is The Last Duel and yes we might know there is a duel, it is not OK in my opinion to show it at the beginning. It is supposed to be something built over time with tension and it's our reward to get it at the appropriate time.
So it is not entirely about spoilers. Imagine the well known duel between Anakin and Obi-Wan. Everyone knows it. Do you think it would have been OK? Can you imagine Revenge of the Sith start with the Obi-Wan and Anakin duel?
Sunset Boulevard, anyone?
Frankly, I don't care how the author uses the method to tell the story, as long as the story is told well.
@Josh Steinberg , your definition of "in media res" is accurate, but it does not mean starting at the end, as in Sunset Boulevard. It would require starting somewhere in the "middle of the story," go into an elaborate flashback, and then proceed to the end.
But I've seen so many films or TV show episodes that start with a scene that's just WTF? How Did Things Manage to Get to This Point? And it's followed by "24 Hours Earlier..." The point isn't that we know what's going to happen, but that we don't know how things will progress in order to get to that point. And more often than not, it whets the appetite instead of ruining it.
