So. When The Return of the King was released, the day before the official release, New Line Cinema held special screenings in a few select theaters around the country.
All three films screened in one day, with hour (or hour-and-a-half) breaks in between (in don’t recall precisely).
The screenings were, for the first two films we all had already seen, the new extended editions, so each was over two hours long. Then there was TROTK screening (which was new to everyone).
New Line Cinema reps were there, handing out gifts. We all got three framed cells of 35mm film cut from one of the original prints of the new film. I still have mine.
It was actually quite amazing, being in a theater packed with people who all wanted to be there. It was breathtaking when the first strains of the LOTR theme played in the dark theater. And people wept openly as TROTK went through its many endings.
What stuck with me was how much the three films felt like one cohesive film when you watched them back to back.
I think we arrived at the theater around 9AM. We left the theater around 10PM (not including jaunts out across the street to grab a burger or something during the intermissions). It was grueling, but it was marvelous, too.
I have a sneaking suspicion that at least in some US states this would be problematic with local health departments. I do not know, but it seems these departments might look askance at Joe Schmo handing an un-verifiably “clean” container into the food service area and hands of the workers.
