I'm thinking of running some 3-D movies here at my theatre and have a few questions. Would I get them from the same bookers as I would go to for the movies I show now? Is there anything different that I should know about the process of running them? Have any of you had success with 3-D and is there a wide selection of movies to choose from?

You will need a silverscreen to project them on to. Matte screens will not work. Also need a lens kit setup. Paramount still has Friday the 13th 3. Jaws 3 and others are still rentable.You could show "It Came From Outerspace" on your matte screen. I saw it about a month ago, terrible splicy print, tons of scratches. I don't like the red/green glasses either, polaroid glasses are the best 3d. We have the lens kit like many other theatres that ran the onslaught of cheesy 1980s 3-d films. However, our silver/aluminum screen was replaced years ago after the fad wore off. An arthouse theatre near me plans on running 3d prints in March, as I am lending them one-sheets to use for the screenings.I will be first in line to see these films!!!!!!! Gotta love 3d.

The 3D systems that use polarization require a "silver" screen that maintains polarization. The analglyph systems that use red and green/cyan lens glasses will work with any screen, but are limited for good color.

The single projector polarization systems put the left eye and right eye images on a single print. The smaller image area and light losses in the polarization filters make it difficult to get a decently bright image. Two projector (interlocked) systems are better, since you have separate prints for each eye, and two projectors lighting the screen.

You need to find out what titles are available, and work with the distributor to identify the suppliers of the special lenses and glasses required. If you've never run 3D before (especially two projector interlock), a service engineer familiar with the technology should help set up the lenses and interlock system.

Thanks for all the input. It will be a great help. Do you think I could hang a silverscreen up in front of my matte screen and then just switch the two when needed? I have the means to raise and lower up to four screens, the theater used to be used for plays and I could use the machanics for the back drops.

Yes, you could hang the silver screen as mentioned. Our theatre used to do the same on the stage. You can use the silver screen for everyday useage, if your auditorium is narrow. Otherwise, you will have a hotspot in the center and too much image loss on the sides. Our auditorium was narrow, so the seats on the side aisles didn't suffer at all. We no longer screen 3-d prints. But, I'd certainly like to run one for a late night show.

Where can I read about what is required to show 3D using one projector? Have people had sucess using a matte screen? I really don't want to purchase a silver screen for something as limited as this. I am using a super simplex projector, so what attachment is required? Any leads to documentation would be appreciated. thanks

As MovieGuy said, the silver screen required for polarized 3D is very high gain, and quite directional, but it can serve as your only screen if the auditorium isn't too wide and if you curve it properly (per SMPTE Recommended Practice RP95). The curved screen is needed to reflect the light back to the center of the audience, minimizing the "hot spots" that would occur if installed flat. If you can get good uniformity, a high gain screen can look really good, and reduce the size of the lamp required to get the SMPTE standard of 16 footlamberts.
